Abstract
Blue light emission of ZnSe thin film from the ZnSe/poly-(N-vinyl-carbazole) (PVK) heterostructures was obtained. The threshold voltage is about 10 V and the brightness of 12 cd/m2 was obtained at 17 V. From the electroluminescence (EL), the photoluminescence (PL), the transient electroluminescence and the dependence of EL intensity on the applied voltage and current, we attribute the EL of ZnSe to carrier injection and recombination. This new phenomenon not only opens a new mechanism of II-IV compounds in low voltage injection EL but also provides a new way of obtaining blue emission.
