摘要:

 采用固相合成法制备了Na0.5Bi4.5–x(Sm0.5Ce0.5)xTi4O15 (NBT–x (Sm, Ce))铋层状无铅压电陶瓷,并研究了(Sm, Ce)3+掺杂对陶瓷材料结构与光电性能的影响。当(Sm, Ce)掺杂到NBT中,陶瓷的相结构和形貌均没有明显变化,而且促进了体系电学性能。当x = 0.008时,其剩余极化强度达到2Pr = 13.33 μC/cm2,同时Curie温度高达640 ℃。(Sm, Ce)掺杂改性后,使NBT陶瓷具有了光致发光特性,室温下表现为明亮的橙色光。在407 nm光的激发下,样品在597 nm波长下出现较强的发射带,对应4G5/2→6H7/2能级跃迁。作为一种多功能材料,(Sm, Ce)掺杂的NBT压电陶瓷在光电器件和传感器等方面有着广阔的应用前景。

 Na0.5Bi4.5–x(Sm0.5Ce0.5)xTi4O15 (NBT–x(Sm, Ce) bismuth-layered lead-free piezoelectric ceramics were fabricated by a solid-state synthesis method, and the influence of (Sm0.5Ce0.5)3+ additive on the structure and electrical/photoluminescence properties of samples was investigated. For the ceramics modified by (Sm0.5Ce0.5)3+ dopants, the phase structure and microstructure have little changes. The electrical properties of ceramics are enhanced. As x = 0.008, the remnant polarization 2Pr reaches 13.33 μC/cm2, and a high Curitemperature TC is 640 ℃. After (Sm0.5Ce0.5)3+ doping, the ceramics show a bright orange photoluminescence. The more intense emission band at 597 nm appears under an excitation at 407 nm, corresponding to the 4G5/2→6H7/2 energy level transition. As a multifunctional material, (Sm0.5Ce0.5)3+-modified NBT piezoelectric ceramics have promising application prospects in optoelectronic devices, sensors, etc..
