Tb3+-doped La1-xAlO3 phosphor powders are successfully synthesized by the solution combustion method, using citric acid as the combustion fuel. The crystal structure and photoluminescence properties of La1-xAlO3:xTb(3+) phosphors are studied, depending on Tb3+ content The strongest emission peak is found at 543 nm, which originates from the D-5(4) -> F-7(5) transition of Tb3+ ions, indicating green emission. Among the fabricated phosphors, the La0.9AlO3:0.1Tb(3+) phosphor emits the strongest green light. The excellent luminescent properties make it a possible candidate for white light-emitting diodes and various photonic applications. (C) 2013 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
