Japanese scientists have developed four times the luminous efficiency of OLED material

The research team, Professor Ikeda Kojun of Osaka Prefecture University in Japan, developed on the first successful high luminous efficiency OLED material. The basic principle is still in the stage, but in the future the luminous efficiency may be as high as four times the current OLED material. It is understood that its structure is simple, low-cost synthesis. The utility model will be used for the purposes of display and lighting.

The newly developed luminescent material is a "methylene cyclo propane" with a benzene ring". As soon as it is exposed to radiation, the electrons of the conductor are separated, and the ring structure is opened and led. If the combination of electronic, spin back to the original ring structure, so durability is good, you can get a long service life.

Prior to this, the research team has been developed with the same structure of light emitting material OLED gamma ray irradiation, but it required special. This time, through the material in the production of frozen to remove the air, etc., the use of general X machine X light, that is successful to make it a green light.

The new OLED material, although it has been confirmed that the light can be irradiated with X light, but the direct irradiation of radiation is not suitable for practical. The future will improve the production of materials and so on, hoping to do as long as the voltage applied to the light.
