中文摘要:
为了研究铌镁酸铅-钛酸铅(PMN-PT)透明电光陶瓷在275~325K下的电光效应,观察了不同尺寸铁电畴的形貌,测量了不同铁电畴尺寸陶瓷的电光系数,从铁电性的角度分析了温度对透明陶瓷电光效应的影响机制,并对不同波段电光陶瓷的电光效应进行表征。结果表明:低温时陶瓷的电光系数较大;电光系数随温度升高而减小,但其变化趋势会因波段不同而略有差异,这从微观上解释了陶瓷介电性能的变化是温度改变导致电光性能发生变化的原因。

英文摘要:
To research the electro-optic effect of lead magnesium niobate-lead titanate(PMN-PT)transparent electro-optic ceramic at different temperatures from 275Kto 325K,ferroelectric domains with different sizes are observed,and electro-optic coefficient of the ceramics with different ferroelectric domain sizes are measured.The influence of temperature on the electro-optic effect is explained from the viewpoint of ferroelectricity.The electrooptic effect the electro-optic ceramic at different wavelengths is characterized.The results show that the electro-optic coefficient of the ceramic is larger at low temperature.The electro-optic coefficient decreases with the increase of the temperature,but the trend varies slightly with different bands,which explains in microcosmic view that the dielectric property variation of the ceramics is the reason of electro-optic characteristic variation due to temperature variation.
