采用溶胶-凝胶法在r切蓝宝石衬底上外延生长了镧改性锆钛酸铅（PLZT）薄膜。溶胶-凝胶溶液中添加甲醇有利于PLZT薄膜的高质量外延生长。该膜显示出几乎与大块PLZT的电光（EO）系数相当的高电光（EO）系数。我们相信这种PUT沉积技术将为未来集成光电器件的数据通信系统打开大门。
Epitaxially grown lanthanum-modified lead zirconate titanate (PLZT) thin films were deposited on r-cut sapphire substrates using an advanced sol-gel method. The methanol addition into sol-gel solutions brought high quality epitaxial growth of PLZT thin films. This film showed high electro-optic (EO) coefficients that were almost comparable to those of bulk PLZTs. We believe this PUT deposition technique will open the door for the future data communication systems with integrated EO devices.
