PLZT纳米薄膜的制备及其特性研究
Preparation and Properties of PLZT Nanometer Thin Film
【摘要】 经溶胶-凝胶法制备出PLZT纳米多层膜,采用热重-差热、X射线衍射、拉曼光谱、SEM等对目标产物进行性能和微结构分析。结果表明:在700℃下保温30min,得到粒径约为50~70nm钙钛矿结构的PLZT纳米薄膜,随Zr含量增大粒径变小,且由三方相向四方相转变。
【Abstract】 The Pb0.93La0.07(ZrxTi1-x)0.93O3(abbreviated as PLZT) thin film was prepared by Sol-gel process.The samples were investigated by TG-DTA,XRD,Rama spectrum and SEM.The results show that the PLZT nanosized thin film with perovskite structure in size of about 50-70nm was obtained at 700℃ sintering for 30min,The particle size of PLZT nanosized thin film decreases and the phases of PLZT nanosized thin film shifts from tetragonal to thombohedral with the increasing of the Zr concentration.
