| 摘 要： | 实验采用溶胶-凝胶法在石英玻璃衬底上制备了掺杂不同钨离子浓度氧化锌薄膜.研究了钨离子的浓度变化对氧化锌薄膜结构与光学性能的影响.测试结果表明,钨离子的掺入使氧化锌薄膜的晶体质量得到提高,衍射峰位置向低衍射角度方向移动,导致薄膜的光学带边发生收缩,即产生＂红移＂现象.随着钨离子浓度增加,氧化锌薄膜光致发光强度表现为先增加而后出现浓度淬灭现象.

| Abstract: | Undoped and W-doped zinc oxide thin films were prepared on quartz substrates by sol-gel process.The effects of tungsten doping on the structure and optical properties of ZnO thin films were investigated.The results suggested that the crystalline quality of ZnO thin films was improved with the doping of tungsten and the peak position was shifted to the lower diffraction angles.The optical band edge of W-doped films showed a red-shift with the increasing in tungsten doping.Moreover,near band edge emission gra... |
