摘要

利用溶胶-凝胶法

在普通载玻片上使用旋转涂膜技术制备了具有

轴择优取向生长的Na-Mg共掺杂的ZnO薄膜。用XRD、SEM、光致发光(PL)及透射光谱对薄膜样品进行了表征。结果表明:Na-Mg共掺杂有利于ZnO薄膜的

轴择优取向生长

并且随着Na

掺杂浓度的增加

晶粒尺寸先增大后减小;通过比较不同掺杂浓度ZnO薄膜的PL谱

推测发光峰值位于380 nm的紫外发射与ZnO的自由激子复合有关;发现掺入Mg的确能使ZnO禁带宽度增大

掺杂组分为Na

0.04

0.2

0.76

O时

其PL谱只有一个很强的紫光发射峰

其近带边紫外光发射强度较未掺杂的ZnO增强了近10倍

极大地提高了薄膜紫外发光性能;并且随Na

浓度增加薄膜透光性减弱。
