Abstract

Transparent BaTiO(3):Eu(3+) films were prepared via a sol-gel method and dip-coating technique, using barium acetate, titanium butoxide, and polyvinylpyrrolidone (PVP) as modifier viscosity. BaTiO(3):Eu(3+) films ~500 nm thick, crystallized after thermal treatment at 700 masculineC. The powders revealed spherical and rod shape morphology. The optical quality of films showed a predominant band at 615 nm under 250 nm excitation. A preliminary luminescent test provided the properties of the Eu(3+) doped BaTiO(3).

摘要

透明 BaTiO(3):Eu(3+) 薄膜采用溶胶-凝胶法和浸涂技术制备，以乙酸钡、钛酸丁酯和聚乙烯吡咯烷酮（PVP）为改性剂粘度。BaTiO(3):Eu(3+) 薄膜厚约 500nm，经 700 摄氏度热处理后结晶。粉末呈现球形和棒状形态。在 250nm 激发下，薄膜的光学质量显示出 615nm 处的主要带。初步的发光测试提供了 Eu(3+)掺杂 BaTiO(3)的性能。
