研究了sm掺杂0.15Pb(Sc1/2Nb1/2)O-3-0.50Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3) （xsm掺杂PSN-PMN-PT）三元多功能陶瓷的晶体结构、电学性能、热稳定性和光学性能。结果表明，随着Sm3+浓度的增加，四方相的体积分数增大。当x = 0.005和0.01时，陶瓷表现为纯钙钛矿结构，Mc相和T相共存。在x = 0.01的条件下获得了最佳的综合性能：T-c、d（33）、k(p)分别约为167℃、682 pC/N和0.61。在30 ~ 110℃的温度范围内，d（33）和k(p)的变化分别只有5%和9.8%。同时，在410 nm激发下，可以检测到以564 nm、599 nm和646 nm为中心的三个不同的发射带，在x = 0.01的陶瓷中检测到最高的强度。结果表明，sm掺杂PSN-PMN-PT体系是一种很有前途的光电器件多功能材料。
The crystal structure, electric properties, thermal stability and optical properties of Sm-doped 0.15Pb(Sc1/2Nb1/2)O-3-0.50Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3) (xSm-doped PSN-PMN-PT) ternary multifunctional ceramics were investigated. It is found that the volume fraction of tetragonal phase increases with the increase in Sm3+ concentration. The ceramics with x = 0.005 and 0.01 show pure perovskite structure with coexistence of Mc and T phases. The optimized comprehensive properties are obtained in x = 0.01 ceramics: T-c, d(33), k(p) are about 167 degrees C, 682 pC/N and 0.61, respectively. In the temperature range of 30-110 degrees C the variations in d(33) and k(p) are only 5% and 9.8%, respectively. Meanwhile, excited by 410 nm, three distinct emission bands centered at 564 nm, 599 nm and 646 nm are detected and the highest intensity is detected in ceramics with x = 0.01. Our results indicate Sm-doped PSN-PMN-PT system is a promising multifunctional material for optical-electric devices applications.
