摘要
本文以金属醇盐[Nb(OC2H5)5]和Fe(NO3) 9H2O为溶胶-凝胶前驱体，采用溶胶-凝胶浸涂法制备了均匀透明的Nb2O5(x)-(1-x)Fe2O3(x = 0、0.6、0.7、0.8、0.9、1.0)薄膜。根据反射光谱，推导出薄膜的折射率和厚度。在Pt/LiClO4-PC(1M)/Nb2O5-Fe2O3ITO电池中，在-2.0 V ~ 1.0 V电势范围内对Nb2O5-Fe2O3薄膜中Li+离子的存储过程进行了电化学研究。在一个循环中插入和提取的总电荷是用循环伏安法测定的。电荷转变能力主要受组分和热处理温度的影响。在纯Nb2O5体系中，560℃热处理1小时后，形成正交晶相。
Preparation and properties of Nb2O5-Fe2O3 sol-gel optical films
In this paper, the homogeneous and transparent Nb2O5(x)-(1-x)Fe2O3(x equals 0, 0.6, 0.7, 0.8, 0.9, 1.0) films were prepared by sol-gel dip-coating method using metal alkoxide [Nb(OC2H5)5] and Fe(NO3) 9H2O as sol-gel precursors. Based on the reflectance spectra, the refractive indexes and thickness of the films were deduced. The electrochemical investigation of Li+ ions storage process in Nb2O5-Fe2O3 films has been made in a Pt/LiClO4-PC(1M)/Nb2O5-Fe2O3ITO cell between -2.0 V and 1.0 V potential range vs SCE. The total electric charge inserted and extracted during a cycle has been determined by the cyclic voltammetries. The electric charge transition ability is mainly influenced by the composition and heat treatment temperature. In pure Nb2O5 system, an orthorhombic crystalline phase presents after heat treated at 560 degrees Celsius for an hour.
