化学沉积AgOx薄膜的透光性能

采用化学沉积法在银一三乙醇胺(TEA)溶液中制备了AgOx薄膜并研究了薄膜的紫外可见光透过性能.实验结果表明,沉积温度越低、沉积时间越短薄膜的厚度越小.AgOx薄膜成份是由Ag、Ag2O和AgO组成的混合相,且薄膜中AgO含量随着第二次TEA与第一次TEA添加量的比值变化而变化.AgO含量越高、薄膜厚度越小,薄膜在紫外、可见光波段的透过率越大.薄膜在300 nm左右出现紫外透过峰,且随着AgO含量增加,峰强度增加,峰位置发生红移;在980 nm附近出现明显的透过峰,峰强随AsO含量增加而增大,最大透过率达到70%.

Light Transmittance of AgOx Thin Films Prepared by Chemical Bath Deposition

AgOx thin films were prepared in Ag+-triethanolamine(TEA) aqueous solutions by using chemical bath deposition method,and the UV-Vis light transmittance of AgOx thin film was investigated.The results showed that low films thickness is corresponded to short time or low-temperature.AgOx film thickness is thinner when it is prepared at lower temperature or in shorter time.The crystallographic phase of deposited film is a mixture of Ag,Ag2O and AgO,and the AgO content of the AgOx films varies with the change of ...
