介绍了在（Pb, La）（Zr, Ti）O3（PLZT）溶胶-凝胶溶液中加入二次溶剂和甲醇预处理蓝宝石衬底的先进溶胶-凝胶方法。对于二次溶剂的添加，添加剂影响PLZT薄膜的结晶度和电光性能，只有甲醇的添加才能改善。此外，甲醇预处理也能有效改善膜的特性。通过这些优化，在r-cut蓝宝石上获得了外延生长的PLZT薄膜，并获得了与大块PLZT相当的高Pockels系数。相信这些PLZT薄膜适用于集成EO器件，为未来的数据通信系统打开了大门。
Advanced sol–gel methods using a secondary solvent addition into (Pb, La)(Zr, Ti)O3(PLZT) sol–gel solution and a methanol pre-treatment of sapphire substrates are demonstrated. For the secondary solvent addition, the additive affected the crystallinity and electro-optic (EO) property of PLZT films and only methanol addition can improve them. In addition, the methanol pre-treatment is also appeared to be effective to improve film characteristics. Through these optimizations, epitaxially grown PLZT thin films on r-cut sapphire are obtained and a high Pockels coefficient which is comparable to those of bulk PLZTs is achieved. It is believed that these PLZT thin films are applicable for integrated EO devices and open the door for the future data communication systems.
