In this paper , the al3 + - doped zno thin films were prepared on na - ca - si glass substrate ( microscope slides ) by sol - gel process from 2 - methoxyethanol solution prepared by zinc acetate as premonitor , monoethanolamine as stabilizator and aluminum chloride reaction . homogenous , transparent , polycrystalline zno thin film was formed finally by diping coating conducted for film - plate on substrate , drying , pre - heat - treatment , anealing 所用的溶胶是以乙二醇甲醚为溶剂，醋酸锌为前驱体，乙醇胺为稳定剂反应制得，用浸渍提拉法在基体上镀膜，经烘烤、预烧、退火，最后形成均匀、透明的多晶zno薄膜。
