摘　　要：使用CdCl_(2)、SeO_(2)和EDTA为原料,借助恒电流脉冲法在碱性环境下成功制备了硒化镉薄膜。通过改变占空比可以实现薄膜表面形貌由纳米颗粒向纳米棒的转变。相比于块体硒化镉,薄膜的吸收边存在着明显的蓝移,得到的硒化镉薄膜具有光致发光特性。Using CdCl_(2),SeO_(2) and EDTA as raw materials,CdSe thin films were successfully prepared in alkaline environment by means of constant current pulse method.By changing the duty cycle,the surface morphology of the films can be transformed from nanoparticles to nanorods.Compared with bulk CdSe,the absorption edge of the thin film has obvious blue shift and has photoluminescence properties.
