摘要

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.
