摘要
The ITO transparent conductive films were prepared on substrate of quartz glass by sol-gel method.The raw materials were nitrate indium,acetylacetone and the dopant of anhydrous chloride(SnCl4).The process from gel to crystalline film and the microstructure of the films were investigated by DTA-TG,XRD and SEM.The influence of preparation processes on the electricity performance of the films was also studied by four-probe apparatus.The results show that the crystallization process of ITO xerogel completes when the heat treatment temperature reaches 600 ℃.The ITO films possesses on vesicular structures accumulated by spherical particles,and both heat treatment temperature and cooling rate have important effects on the resistivity of ITO films.
