煅烧工艺对氧化锌铝（AZO）粉体光学性能的影响
Source abstract
Abstract
采用聚丙烯酰胺凝胶法制备高浓度Al掺杂ZnO(AZO)前驱体( x (Al)=5.5mol%、6.5mol%), 研究煅烧工艺对AZO粉体光学性能的影响. 结果表明: 随着煅烧温度升高, Al在ZnO中的固溶度降低。当煅烧温度为750℃时, 生成ZnAl 2 O 4 相。提高煅烧温度, 粉体的紫外吸收峰从366 nm红移至373 nm; 延长煅烧时间, 紫外吸收峰发生蓝移, 吸收强度明显增大。室温下AZO粉体光致发光(PL)光谱主要由354 nm的紫外发射峰、406 nm的近边紫外发射峰和430 nm的蓝光发射峰组成。
