Abstract
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:xTb3+ phosphors are studied, depending on Tb3+ content. The strongest emission peak is found at 543 nm, which originates from the 5D4→7F5 transition of Tb3+ ions, indicating green emission. Among the fabricated phosphors, the La0.9AlO3:0.1Tb3+ phosphor emits the strongest green light. The excellent luminescent properties make it a possible candidate for white light-emitting diodes and various photonic applications.
