Improved Preparation Method and Luminescence Properties of LuTaO4:Ln3+(Ln=Eu,Tb) Thin Film

doi:10.15541/jim20150503

Abstract

Abstract:

LuTaO₄ is a kind of novel material for radiation detectors, but using it to prepare high-quality and transparent thin film is of great challenges. In our previous study, high-quality LuTaO₄ thin film was prepared with thickness of single film only about 60 nm, but multilayers film easy to crack. In this study, to ensure no cracking and high transparency of thin film, PVP was chosen as adhesive and single LuTaO₄:Ln³⁺(Ln=Eu,Tb) film of 100 nm was prepared by modulating solid and PVP content through lots of exploration, with improved luminescence properties and high transparency simultaneously. This method lays the foundations for preparation of high-quality applicable LuTaO₄:Ln³⁺(Ln=Eu,Tb) thick film.

Key words: LuTaO4:Ln3+(Ln=Eu,Tb) thin film, Sol-Gel method, solid content, PVP, luminescence properties
