Russian Physicists increase life span of OLEDs Using Nano Crystals of Cadmium Chalcogenides

Russian physicists have developed an advanced technique for creating long lasting organic light-emitting diodes (OLEDs).

OLEDs have several advantages over all other kinds of light emitting devices. But the major drawback of OLEDs is their short span of life. This happens because, organic Chromophores, which cannot live for long, mainly construct the emitting sites for OLEDs.

To resolve this problem the Russian physicists have added longer living nano crystals of inorganic luminescent sites Cadmium Chalcogenides to the normal OLEDs.

The Cadmium Chalcogenides nano crystals do not easily collapse at the time of exploitation due to their very strong bonds. Moreover, when the size of these strongly bonded nano-crystals change the wavelength of their luminescence also changes.

Russian scientists recommend replacing the short living organic Chromophores with the longer living inorganic luminescent component on the basis of the nano crystals which act as semiconductor.

This new technique developed by the Russian physicists has made the manufacturing process of long living OLEDs much simpler as well.
