Fundamentals in Organic Light Emitting Diodes

晶体管和激光等固态电子设备一直在不断地改变着我们今天生活的社会。然而，固态发光设备并没有战胜爱迪生的白炽灯。灯泡非常浪费；大约98%的能量输入最终以热而不是光的形式结束。美国能源部估计，如果广泛采用节能固态照明，将提供约190太瓦时的节能，这将减少温室气体排放3140万吨碳。这项建议的重点是研究表面和界面材料，这是开发简单高效的有机发光二极管(OLED)的关键，从而有助于加快从灯泡到固态照明的过渡。具体地说，这项建议的NSERC发现研究计划

Solid-state electronic devices such as transistors and lasers have been continuously transforming the society we live in today. Solid-state light-emitting devices, however, has not conquered Edison's incandescent light bulbs. The light bulbs are quite wasteful; some 98% of the energy input ends up as heat instead of light. US department of Energy has estimated that energy efficient solid-state lightings, if broadly adopted, would provide approximately 190 terawatt-hours in energy saving, which would reduce green house emissions by 31.4 million metric tons of carbon. This proposal is to focus on studying surface and interface materials which are key to develop simple and efficient organic light emitting diodes (OLED) and thus would help accelerate the transition from bulb to solid-state lightings. Specifically, this proposed NSERC discovery research program
