Russian physicists use Nanocrysal to make long-life OLEDs

Russian physicists has found a new way to make a long-living OLED. They are using nano-crystals of cadmium chalcogenides instead of the organic Chromophores in the OLEDs. Those Nanocrystals are long-lasting and when their size change, luminescence wavelength also changes, so it is easy to get required emission wavelength. They physicists say that the manufacturing process of the new devices is very similar to regular OLEDs, there's only one change in the process, when colloid solution of semiconductor nano-crystals is mixed with organic semiconductor.
