Optically pumped stimulated emission behavior was demonstrated in a slab waveguide structure formed by substrate/organic film/air. The organic film was deposit
White color emitting organic electroluminescence (EL) device is a convenient means to realize full-color display because the three necessary primary colors coul
In order to use organic light emitting devices (OLEDs) in display application , it is very important to obtain red emitting light. There are two methods for o
The operating mechanisms of the OLEDs involve injection of electrons and holes from the electrodes, and electron hole recombination which emits the light. To
