Synthesis and Luminescence Properties of BaAl2B2O7:RE (RE = Dy3+ and Sm3+) for Optoelectronic Application

Abstract

BaAl₂B₂O₇ powders activated by RE³⁺ ions (Dy³⁺ and Sm³⁺) were prepared by the solution combustion method. X-ray powder diff raction analysis was used to conduct the phase studies for BaAl₂B₂O₇:Dy³⁺ and BaAl₂B₂O₇:Sm³⁺. A spectrofluorometer operating at room temperature was used to examine the luminescence characteristics of the prepared materials. Under excitation of 350 nm, BaAl₂B₂O₇:Dy³⁺ emitted at 482, 574, and 664 nm, whereas the other phosphor, BaAl₂B₂O₇:Sm³⁺, emitted at 564, 600, 646, and 710 nm following excitation at 402 nm. Thus, this inquiry led to the preparation of two new optical materials that emit visible-spectrum light.
