چکیده مقاله:
light emitting diodes ( OLEDs) are one the newest lighting in industrial lighting wich can be a promising candidate in this area. A typical reverse OLED is made from cathode, injection/transport electron and hole layers , emissive layer (EM) and. Electrons and holes after injection to EM, recombinate in emissive layer which is an organic material. In reverse structure, holes inject EM well while electrons cannot be easily injected to emissive layer. Here, effect of lithium doped zin oxide (LZO) on the led performance was investigated. The results showed that lithium can be increased conductivity of injection electron layer and facile to inject electron to emissive layer.
