“It can potentially revolutionize lighting technology,” said Assistant Professor of Industrial and Manufacturing Engineering Zhibin Yu. “In general, the cost of LED lighting has been a big concern thus far. Energy savings have not balanced out high costs. This could change that.”
Yu developed this new LED technology using a combination of organic and inorganic materials. The material, which dissolves and can be applied like paint, shines a blue, green or red light and can be used to make a light bulb. But what makes it really special is that it’s far simpler to manufacture than existing products on the market.
Most LED materials require engineers to put 4 or 5 layers of material on top of each other to create the desired product or effect. Yu’s material only requires 1 layer.
The research is crucial to the development of LED technology, which is fast becoming an avenue to reduce the country’s electric consumption. LED lighting is already sold in stores, but widespread adoption has been slow because of the costs associated with the material and the quality. But, LED lights do save energy. According to the U.S. Department of Energy, residential LED lighting uses at least 75% less energy than regular incandescent lighting. http://www.newswise.com/articles/researcher-develops-cheaper-better-led-technology
Organometal halide perovskite and poly(ethylene oxide) composite thin films are studied. Single-layer light-emitting diodes using the composite thin film sandwiched between indium tin oxide and indium-gallium eutectic alloy exhibit a low turn-on voltage and high brightness because of the ionic conductivity of the composite film and the formation of a p-i-n homojunction.
