用电子束蒸发的方法制备了富锌的氧化锌薄膜, 在室温下测量了它的光致发光和电致发光光谱, 发现光致发光主要集中在近紫外(UV)区. 而电致发光光谱中, 出现了近紫外发射峰和蓝色发射带, 并且在电场调制下发光出现了场致猝灭现象. 电致发光中蓝色发射带的位置与用低压MOCVD方法制备的富锌的氧化锌薄膜的电致发光相比有较大的蓝移. 这些结果表明在用所设计方案制备的器件中, 富锌型氧化锌薄膜可以产生大于禁带宽度的过热电子能量, 是获得UV及蓝光发射的一种具有新机理的、有希望的新途径. ZnO thin films were prepared by electron beam evaporation and their photoluminescence and electroluminescence spectra were measured at room temperature. It was found that the photoluminescence mainly concentrated in the near ultraviolet (UV) region. The electroluminescence spectra , Near-UV emission peaks and blue emission bands appeared, and field quenching occurred under the electric field modulation.The location of the blue emission band in electroluminescence and zinc-rich zinc oxide prepared by low-pressure MOCVD The results show that zinc-rich zinc oxide thin films can generate overheating electron energy larger than the forbidden band width in the devices prepared by the designed scheme, which is to obtain UV and blue light emission A promising new approach with new mechanisms.
