在室温下研究了不同PT含量（x=6、10、13%）的PMN-xPT单晶弛豫固溶体和首次合成的La含量为3%的PLMN-25PT透明陶瓷的电光性能。已经表明，单晶中二次电光系数对 PT 浓度的依赖性达到最大 atx∼13%。研究表明，尽管PLMN-25PT陶瓷中的PT浓度高于13%，但该材料在所有已知弛豫系统中表现出最大的二次电光系数和最低的半波电压。已经讨论了上述现象的可能根源。
The electro-optical properties of the PMN-xPT single-crystal relaxor solid solutions with different PT contents (x= 6, 10, 13%) and the PLMN-25PT transparent ceramic with a La content of 3%, which has been synthesized for the first time, have been studied at room temperature. It has been shown that the dependence of the quadratic electro-optical coefficients on the PT concentration in single crystals passes through a maximum atx∼ 13%. It has been revealed that, although the PT concentration in the PLMN-25PT ceramic is above 13%, this material exhibits the largest quadratic electro-optical coefficients and the lowest half-wave voltage among all the known relaxor systems. Possible origins of the above phenomena have been discussed.
