Japan developed a luminous efficiency of 86% OLED material

According to international journal "Nature Photonics" professional optoelectronic Kyushu University published "the most apex organic photoelectric research center (OPERA)" Professor anda thousand wave led research team developed the emission rate as high as 86% of the OLED material. The new material is suitable for organic molecules with a luminous energy state from 25% to a substantial increase of up to 86.5%. In addition, an important feature of the new material is not the use of precious metal iridium. The advent of this new type of OLED materials, will enable the development of a new generation of low-power TV and LED lighting equipment much anticipated.

The new material is made up of two kinds of molecules, according to the phenomenon of "compound excitation (Exciplex)", which makes the energy move and move between the neighboring molecules. In the past, in the field of OLED, has been considered to reduce the luminous efficiency of this phenomenon, the study subvert this common sense".
