摘要

研究了选定成分的PLZT彩虹陶瓷的压电、热释电和光电性能。实验发现，在圆顶模式下，彩虹样品具有很强的压电效应。在发生机械共振之前，随着频率的增加，压电响应逐渐减小。由于彩虹的圆顶结构与压电效应的耦合作用，样品的热释电性能略有提高。彩虹陶瓷的圆顶结构和内应力对其光伏和光导特性的影响很小。

The piezoelectric, pyroelectric and photoelectronic properties of PLZT Rainbow ceramics

The piezoelectric, pyroelectric and photoelectronic properties of PLZT Rainbow ceramics of selected compositions were investigated. It was found that the Rainbow samples had a very strong piezoelectric effect when operated in the dome mode. The piezoelectric response decreased gradually with increasing frequency before occurrence of mechanical resonances. The pyroelectric properties of the samples were slightly enhanced due to the coupling of the Rainbow's domed structure with the piezoelectric effect. The domed structure and internal stress of Rainbow ceramics had a minimal impact on their photovoltaic and photoconductive characteristics.
