| 摘要: 通过高温固相反应法制备了Ba0.85Ca0.15Ti0.90Zr0.10O3∶xSm3+(BCTZ∶xSm3+，x=0.0%、0.2%、0.4%、0.6%、0.8%、1.0%，物质的量分数)陶瓷，系统研究了其微观形貌、铁电性能、储能性能和光致发光性能。研究表明，Sm3+掺入后，陶瓷平均晶粒大小明显下降，致密度显著提高。所有陶瓷均表现出典型的铁电性。BCTZ∶xSm3+陶瓷放电储能密度得到了极大的提高，BCTZ∶1.0% Sm3+陶瓷放电储能密度较纯BCTZ陶瓷可提高约49.0%。此外，在408 nm光的激发下，BCTZ∶xSm3+陶瓷在596 nm左右表现出强烈的橙红色发光，且发光强度相对可调性可达449%。 |

| Abstract: Sm3+-doped Ba0.85Ca0.15Ti0.90Zr0.10O3 (BCTZ∶xSm3+, x=0.0%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, mole fraction) ceramics were synthesized using the conventional solid state reaction method, and their microstructure, ferroelectricity, energy storage performance, and photoluminescence (PL) properties were systematically investigated. The results showed that the mean grain size of the ceramics decreased obviously and the density increased significantly after the addition of Sm3+. All ceramics exhibited typical ferroelectric properties. Moreover, with the further increase of doping amount, the remanent polarization (Pr) gradually decreased to 8.432 μC·cm-2 (BCTZ: 1.0%Sm3+), and the ferroelectricity was suppressed. The energy storage density of BCTZ∶1.0%Sm3+ ceramic was improved by ca. 49.0% compared with that of pure BCTZ ceramic. In addition, BCTZ∶xSm3+ceramics exhibit strong orange-red luminescence at about 596 nm under light excitation at 408 nm, and the PL intensity can be adjusted by 449%. |
