采用Sol-gel法在普通载玻片上制备YZO薄膜。研究了陈化时间和Y掺杂量对薄膜晶体结构、表面形貌和光学性能的影响,并分析和探讨了工艺参数与结构和性能之间的关系。实验结果表明,YZO薄膜为纤锌矿结构,呈C轴择优取向生长,平均透光率(380~760m)超过85%。实验还发现,陈化时间存在最优值,YZO薄膜随着Y掺杂量的增加晶体结晶质量下降。
Yttrium-doped zinc oxide thin films on glass substrates are prepared by the sol-gel process. The effects of the aging time and yttrium dopant concentration on the structure, morphology and optical properties of the thin films are investigated. The results show that YZO thin films have hexagonal wurtzite structure with high c-axis orientation. The average transmittance of YZO thin films in the visible range (380~760nm) is beyond 85%. The best aging time is 72b, The crystal quality of YZO thin films is decreased with the increase of the dopant concentration.
