( 2 ) in ( no3 ) 3 was dissolved in acetylacetone in the mol ratio of l : 3 . they were mixed for about 3 hours to obtain acetylacetone salts . then glycol methyl aether was added in the ratio of 1 : 40 to obtain indium oxide sol . sncl4 was dissolved in glycol methyl aether and then added into the indium oxide sol to prepare transparent and stable ito sol ( 2 )通过将铟的无机盐硝酸铟与乙酰丙酮按摩尔比1 : 3 ,混合搅拌3h左右得到铟的乙酰丙酮盐,然后按一定摩尔比加入乙二醇独甲醚溶液,混合搅拌制得氧化铟溶胶,再将一定量的sncl _ 4溶入乙二醇独甲醚,掺入氧化铟溶胶制得透明稳定的掺锡氧化铟溶胶( ito溶胶) ,该溶胶性能稳定,易于成膜。
