Sodium bismuth titanate-based dielectric ceramic with energy storage and fluorescence characteristics and preparation method thereof
The invention discloses a sodium bismuth titanate-based dielectric ceramic with energy storage and fluorescence characteristics, the chemical composition general formula is 0.75 Bi < 0.5-x > M '< x > Na < 0.5 > TiO < 3-0.25 > Sr < 0.7 > M' < 0.1 + y > TiO < 3 >, x is equal to 0-0.3, y is equal to 0-0.3, M 'adopts a trivalent rare earth element, and the trivalent rare earth element is one, any two or a combination of any more than two of Dy < 3 + >, Eu < 3 + >, Ce < 3 + > and Sm < 3 + >; m ''is any one or two of Bi < 3 + > and La < 3 + >; the invention further discloses a preparation method of the sodium bismuth titanate-based dielectric ceramic with energy storage and fluorescence characteristics. The problems that existing energy storage-fluorescence ferroelectric ceramic is low in energy density, large in fluorescence color regulation and control difficulty and low in luminous intensity are solved.
本发明公开了兼具储能和荧光特性的钛酸铋钠基介电陶瓷，化学组成通式为0.75Bi0.5‑xM′xNa0.5TiO3‑0.25Sr0.7M″0.1+yTiO3，x＝0～0.3，y＝0～0.3，M′采用三价稀土元素，三价稀土元素为Dy3+、Eu3+、Ce3+、Sm3+元素中的一种、或任意两种、或任意两种以上的组合；M″为Bi3+、La3+元素中的任意一种或两种；本发明还公开了兼具储能和荧光特性的钛酸铋钠基介电陶瓷的制备方法，本发明解决了现有储能‑荧光铁电陶瓷存在能密度低、荧光光色调控难度大、发光强度低的问题。
