摘要:The main task in the development of light-emitting layers for organic light emitting diodes (OLEDs) is to achieve a high efficiency of conversion of the electronic excitation energy to the energy of light emission, which is originated from the electron-hole recombination.

In this talk, the approaches that could be useful for design of light-emitting layers for OLEDs will be presented. The sequences of events caused by electron-hole recombination will be analyzed and perspectives of their use in OLED development will be discussed.

The following topics, which are important for the development of OLEDs, will be assessed:

•General scheme of electronic processes in light-emitting layer.

•The electronic excitation energy transfer (EEET) in polymer matrix. The   role of intrinsic (including excitonic) traps.

•The problems of interpretation of EEET in polymeric media.

•Some approaches to increase the quantum yield of light-emitting  layers.     

•Development of single molecular white OLED (WOLED).

简历:Prof. Dr. Valeriy M. Yashchuk is a Head of Experimental Physics Department of Taras Shevchenko National University of Kyiv, Kyiv, Ukraine. He holds his Ph.D. and Doctor of Sciences (D.Sc.) degrees in physics from the same university. His scientific expertise lies in a field of area of photonics of organic media, he has published more than 250 peer-reviewed articles in this and related domains.

Prof. Yashchuk’s current research interests include:

• Electronic excitation energy transfer in macromolecules
