Abstract

The optical properties of near ultraviolet light emitting diodes (UV LED) fabricated by ZnO/GaN heterostructures were discussed. The ZnO films were grown by ablating sintered ZnO with pulsed Nd:YAG laser. Current-voltage (I-V) photoluminescence (PL) and electroluminescence (EL) measurements were performed. The results show emission peaks which are centered at 3.229 eV and 3.394 eV when electroluminescence spectrum was studied.
