Optimization of the Photoluminescence Properties of Electrodeposited Y_2O_3: Eu~(3+) Thin-Film Phosphors

摘要

In this work, electrodeposition is proved to be a promising method to prepare Y_2O_3:Eu~(3+) thin-film phosphors. The photoluminescence (PL) property of the Y_2O_3:Eu~(3+) thin-film phosphor strongly depends on different factors such as the crystal structure of host materials, annealing temperature, and doping concentration of Eu3+. The best PL performance of the Y_2O_3:Eu~(3+) thin-film phosphor is achieved for a sample annealed at 600℃ with a Eu~(3+) doping concentration of 1.85 atom%.
