摘　　要：用溶胶－凝胶技术制备了组分为９／６５／３５的ＰＬＺＴ非晶薄膜，这类薄膜具有类铁电性。在２００～７００ｎｍ的波长范围内测试了ＰＬＺＴ类铁电非晶薄膜和同样组分的透明陶瓷的椭偏光谱，得到了其光学常数谱（折射率ｎ谱和消光系数ｋ谱）。PLZT amorphous films whose composition is stoichiometric 9/65/35 have been grown and they show some wonderful ferroelectriclike properties.The ellipsometric spectra of PLZT ferroelectriclike amorphous films and transparent ceramics whose composition is also 9/65/35 have been obtained by a homemade automatic ellipsometer in the 200700nm wavelength range,and their optical constant spectra (refractive index n spectra and extinction coefficient k spectra) have been determined in the same range.Their absorption edges and some optical properties have been compared and discussed.
