Abstract
In this paper, influences of poly (N-vinyl-carbazole) (PVK) on the emission properties of zinc selenide (ZnSe)-based organic-inorganic heterostructure devices have been studied. A broad band emission peak at 443 nm, with shoulders at 520 and 595 nm, was observed from ITO/PVK(80 nm)/ZnSe(120 nm)/Alq3(15 nm)/Al under electric fields and it consisted of emissions from PVK, ZnSe and Alq3 layers. Therefore, a charge carrier injection luminescence in ZnSe layer is suggested. By changing the thickness of PVK layer and/or ZnSe layer, the roles of PVK in the device were discussed.
