摘要: 本文主要研究退火处理对ZnO:Ag样品相关性质的影响。在700℃的条件下，对ZnO:Ag样品进行20 min的退火处理；利用X射线衍射仪(XRD)研究样品晶格结构的特性，拉曼光谱(Raman)研究样品内部的应力作用，光致发光谱(PL)研究样品的光学特性。经过退火处理后，样品六方纤锌矿结构得到了保持，ZnO(0002)晶向的峰位发生了偏移，Ag掺杂导致的晶格张应力得到释放。ZnO:Ag样品中544 nm和612 nm处的两个尖锐发光峰经过退火处理后减弱。
Abstract: In this paper, the effects of annealing on the properties of Ag doped ZnO samples are studied. Ag doped ZnO samples are treated with rapid annealing process at 700˚C for 20 minutes. The crystal structures of ZnO:Ag films are investigated by X-ray diffraction (XRD). And Raman spectra are performed to study the inside stress effect. The optical properties of samples are determined by photoluminescence spectrum (PL). The hexagonal wurtzite structure of ZnO remains after an-nealing, while there is a shift of the peak position of ZnO(0002), which may be caused by the lattice tensile stress released after Ag doping. In particular, two sharp peaks at 544 nm and 612 nm in ZnO:Ag samples are reduced after annealing.
