Liao Liangsheng's Main Achievements and Technical Contributions

Up to February, 2009, more than 100 academic papers were published, among which the citation times of SCI source journals exceeded 1.350 times (H- index was 1.9), and four papers were cited more than 1.00 times. During my eight years in Kodak, my research results were mainly published in the form of patents and internal communication reports: I applied for more than 50 American patents (24 of which were authorized); More than 65,438+000 other patents have been applied (90 of which have been authorized or published: 22 in China, 23 in Europe, 4 in Germany, 24 in Japan and 65,438+07 in South Korea); Published more than 80 internal communication reports. It has made important contributions to the research of organic light-emitting display technology and organic solid-state lighting technology of Kodak Company in the United States. The main technical contributions include:

First, cascaded organic light emitting diodes (U.S. Pat.No. 6,872,472b2; U.S. Pat. No.6,936,961B2; Applied physics, litt. 2004, 84, 167; Citation times: 102), which provides a new device structure for preparing large-area long-life organic light-emitting displays and organic solid-state lighting devices.

Secondly, high efficiency organic electroluminescence is obtained: the current efficiency is 400 cd/A and the external quantum efficiency is close to 100%.

Thirdly, red, green and blue organic electroluminescent (fluorescent) display devices with high performance are manufactured (ICEL-6 invitation report, 2006); An organic white light illumination device (SID'08 Digest 200818) with high efficiency and long life was prepared. Participated in the preparation of organic white lighting devices with power efficiency of 60 lm/W, brightness 1 000 cd/m2 and half brightness life 1 0,000 hours or more.

Fourthly, the characteristics of coherent light in the electroluminescence of cascaded organic light-emitting diodes are studied, which makes the research of organic laser diodes a step forward. Ritter. 2005, 30, 3072).

Fifthly, an organic photodetector with extremely low dark current is prepared.

Sixth, photoluminescence (appl.phys.lett.1996,68850; Citation times: 174).
