Eu-doped BaTiO₃powder and film from sol-gel process with polyvinylpyrrolidone additive

Int J Mol Sci. 2009 Sep 17;10(9):4088-4101. doi: 10.3390/ijms10094088.

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).

Keywords: BaTiO3; europium; films; luminescence; sol-gel.
