Influence of Annealing on Microstructure and Photoluminescence Properties of Al-Doped ZnO Films Li Yan1,Cheng Hang1,Xie Juan1,Xu Ziqiang1,Deng Hong1 (1.School of Microelectronics and Solid-State Electronics, University of Electronic Science and Technology of China, Chengdu 610054, China) Abstract:Effect of annealing temperature and time on the microstructure and photoluminescence (PL......
of the glasses were investigated. SrO-ZnO-B2O3-SiO2(SZBS) glass has high transmission capability in visible light region. The excitation peak of SZBS glass locates around 221 nm. The photoluminescence spectrum... hole recombination process, respectively. Besides the excitation peak appears red-shift, the transmission ratio of glasses improves and the blue-green photoluminescence enhances with rare earth oxides......
