摘要 用溶胶-凝胶法在单晶Si、PLT/Si、PT/Si以及经过质子交换后的LiNbO3基片上制备了锆钛酸铅(PZT)铁电薄膜,分析了界面扩散以及Pb含量对薄膜晶化的影响。在试验中,通过适当添加过量的Pb(CH3COO)2可以防止缺Pb焦绿石相的形成。 Lead zirconate titanate (PZT) thin films are prepared on the substrates of monocrystal Si,PLT/Si,PT/Si/and proton-exchanged(PE)LiNbO3 by sol-gel process.Interface diffusion and the effect of Pb content on the films crystallization were investigated.In all cases,excess Pb(CH3COO)2 was added to avoid the formation of pb-deficient pyrochlore.
