University of Michigan Researchers Develop Metal-free Phosphorescent OLED
LIGHTimes News Staff
July 17, 2014...Researchers from the University of Michigan claim to have produced a
metal-free Phosphorescent OLED. The researchers note that fluorescent LEDs can
produce light from up to 25 percent of the electrons that pass through them.
However, phosphorescent organic LEDs can potentially turn every electron into a
ray of light, but achieving this efficiency with inexpensive materials is
The researchers note that while carbon-based, or organic, semiconductors are
much cheaper than inorganic semiconductors, today's organic technologies employ
metals in the semiconductor to enable phosphorescence. According to the
researchers, these metals and their incorporation into the semiconductor
material raises the price and sometimes makes the material toxic. Now, the team
led by Jinsang Kim, a professor of materials science and engineering, has
devised bright, metal-free, phosphorescent OLEDs.
The difficulty was getting the semiconductors to produce light rather than
heat. The researcher pointed out that electrical charges in a semiconductor can
produce light in one of two ways. About one in four of the charges can cause
fluorescence, resulting in the 25 percent efficiency limit for fluorescent
LEDs. The other three in four can go towards phosphorescence, emitting slightly
lower energy light than fluorescence, the researchers said.
Organic semiconductors reportedly tend to loose about 75 percent of the
energy from electricity in producing phosphorescence. Instead of creating
light, 75 percent of the electrons generate vibrations in the surrounding
molecules, heating the material. The researchers note that while incorporating
metals can improve phosphorescent emission efficiency, going metal-free
requires a different solution.
"That's why phosphorescence from metal-free organic materials in nature is
very rare," said Min Sang Kwon, a materials science and engineering postdoc in
Kim's lab. One example, he added, is the Hope Diamond.
The researchers indicated that the phosphorescent OLEDs that they developed
can reveal the presence of water under backlight. Water reportedly causes the
polymers in the phosphorescent OLED they created to break, changing the
material's phosphorescent light (green) to fluorescent light (blue), according
to the researchers.
The team demonstrated that the stiff lattice structure of the OLED they
created helps to stifle vibrations so more energy could be released as light.
The material's crystals produced light from 55 percent of the charges. However,
according to the researchers, it is very difficult to produce high-quality
crystals consistently in manufacturing.
The researchers altered the molecules so that they would structurally bond
with a transparent polymer. The team heated and dried a solution containing the
new phosphorescent OLEDs and polymers, and the molecules assembled themselves
into a stiff matrix. This structure allowed 24 percent of the charges to
produce light. While this efficiency level is only about as good as fluorescent
light, the team is attempting to devise a complementary way to improve the
"We demonstrated that increasing the intermolecular bonding strength
could efficiently suppress the vibrational loss of the phosphorescent
light," said Kim. "This finding provides an insight into molecular
designs for achieving energy-efficient and inexpensive light-emitters, ideal
for practical devices."
The presence of water reportedly breaks up the bonds that enable the charges
to fluoresces (producing green light in this material). However, when the bonds
break, the OLED switches to the fluorescent mode, emitting blue light.
"We can see the change from phosphorescence to fluorescence, and we know
some water is there," said Kwon.
The material could lead to simple sensors for detecting water. The
researchers detailed their findings in a paper in Angewandte Chemie. The
Samsung Global Outreach grant funded the research.

Lakewood Church Upgrades Displays with Higher Resolution Daktronics LED Video Displays
LIGHTimes News Staff
July 17, 2014...Lakewood Church in Houston, Texas got two new LED video displays from
Daktronics Inc. of Brookings, South Dakota USA. Daktronics designed,
manufactured and installed two new LED video displays to replace the existing
Daktronics displays with a higher resolution display that features 4-millimeter
line spacing in a full black package.
The church uses the displays to show inspirational images and stories during
service or reveal IMAG (Image Magnification) shots as well as live video of the
sermon and song lyrics that allow the congregation to follow along. The feed
shown on the new LED displays is the same video shown on the video displays
inside the church.
The display installation continues the nine-year relationship between
Lakewood Church and Daktronics. The installation employs the existing structure
to support the new displays that measure more than 12-feet high by 22-feet wide
that replaces the two previously installed 8-millimeter pitch displays
positioned on each side of the main service platform. Installing each display
took roughly five days between Dec. 1 and Dec. 13.
"We started tearing down one of the old displays after the final service
on Sunday and had the new display installed and operational before the Saturday
service at the end of the week," said Nathan McGillivray, Daktronics
project manager of the installation. "It was critical for Lakewood to have
zero display downtime, so we installed one display the first week and the other
display the following week. Services went off without a hitch and with full
video display functionality."
"After the displays were installed, the wardrobe and makeup departments
had to be notified of everything that was now visible on the new
high-definition displays," said Joel Henie, Daktronics sales
Henie said, "A trip to the recent installation at Saddleback Church
really helped confirm Lakewood's choice to upgrade with Daktronics."
The upgrade reportedly offers image clarity and contrast that now makes
everything much more visible to the audience, from lint on clothing to blotches
of makeup and powder.

The B.O.S.E. Consortium offers two different licensing schemes: a
“Device License” for the use of the white LED light technology
covers the application of the silicate phosphor to a blue LED and a
“Material License” for manufacturing and marketing of the silicate
phosphor materials. TG has reportedly granted a device license to Harvatek, a
Taiwanese LED company, to employ the patented white LED technology.
The License Agreement between TG and Harvatek allows Harvatek to manufacture
and offer white LEDs using silicate phosphors covered by licensed patents.
Through the license agreement, Harvatek now joins the pool of white LED
manufacturers having licensed B.O.S.E. Consortium’s silicate-based white
LED patent family. Harvatek and TG reportedly look forward to exploring new
business opportunities and future cooperation based on the agreement.

"Following the enormous success of the launch of Pulsaderm and Pulsaderm
Buddy facial cleansing brushes, adding Pulsaderm LED Blue seems like a natural
addition to the brand's growing line of affordable and effective beauty
The device employs blue light at a wavelength of 415 nanometers (nm). At the
device's light frequency and intensity, the light penetrates into the skin's
pores to activate light-sensitive porphyrins, in the outer cell membranes of
acne or acne-causing bacteria. Certain wavelengths of light cause porphyrins to
produce free radicals. These free radicals ultimately kill the acne-causing
bacteria without harming healthy skin. The device utilizes 97 non-damaging LED
lights for nearly four times as much power as most of its competitors.
According to the company, the brightness guarantees faster results for clearer,
blemish-free skin. Blue light therapy is 100 percent natural, non-invasive and
drug-free acne treatment process with no short-term or long-term adverse side
effects. The company boasts that the gentle and painless therapy reveals
visible improvements with each use.
"With innovative advancements serving as the backbone of Pulsaderm, it's
in the brand's DNA to revolutionize skincare," added von Berg. "All of
the Pulsaderm products were created in an effort to prevent and resolve
skincare problems at affordable prices. By incorporating the latest
cutting-edge technology in each product throughout the line, Pulsaderm aims to
deliver a new sense of clean."
