摘要

采用固相烧结法制备了Eu

掺杂的铌酸钠钾（KNN）陶瓷。用X射线粉末衍射仪、荧光光谱测试仪和LCR精确阻抗测试仪等对其结构、发光性能和介电性能进行表征。XRD结果显示样品为钙钛矿结构。荧光分析结果表明，致密度对KNN陶瓷材料发光性能有一定的影响，Eu

掺杂量是影响其发光性能的重要因素。其中掺杂Eu摩尔分数为4%的样品在930℃焙烧后其发光最强，在396 nm紫外光激发下，发射光谱最强峰在614 nm，对应于Eu

电偶极跃迁。样品经3 kV/cm、110℃极化30 min后进行压电性能检测，结果表明提高Eu

掺杂量以及陶瓷的致密度，可改善压电性能。其中掺杂4%Eu的KNN压电常数

最大为98 pC/N，在1 kHz、100℃时，介电常数最小为217，介电损耗tan

Abstract

doped potassium-sodium niobate(KNN) ceramics were fabricated by a solid-state reaction method. X-ray diffraction

photoluminescence spectra and LCR meter were used to characterize the structure and properties of Eu

doped KNN ceramics. XRD results show that the obtained KNN ceramics are orthogonal architecture. The relative density and Eu

doping concentration can affect the luminescent properties of KNN ceramics

doping mole fraction is a key factor. 4% Eu

doped KNN ceramics at 930℃ sintering temperature has excellent red-orange luminescence under 396 nm excitation

and the strongest emission peak is located at 614 nm

corresponding to

transition of Eu

. The piezoelectric properties of all samples are measured after polarized at 3 kV/cm and 110℃ for 30 min. The results reveal that the piezoelectric properties can be improved by increasing the Eu

content and the ceramics relative density. KNN-4%Eu

ceramics shows good piezoelectric and dielectric performance. Piezoelectric constant

reaches up to 98 pC/N

dielectric constant

is 217

dielectric loss tan

is 0.199(1 kHz

100℃) and Curie temperature

is 426℃.
