The objective of this study was to investigate the photoluminescence properties of Al4B2O9:M (M = Dy3+, Sm3+, and Tb3+). The solution combustion method was employed to prepare Al4B2O9 doped with M ions. The synthesized aluminum borates were subjected to phase analysis using X-ray diffraction, while their photoluminescence properties were evaluated using a spectrofluorometer. Under excitation at 352 nm, Al4B2O9:Dy3+ exhibited emission peaks at 484, 578, and 701 nm. Similarly, when excited at 402 nm, Al4B2O9:Sm3+ emitted light at 563, 599, 645, and 702 nm. Finally, upon excitation at 238 nm, Al4B2O9:Tb3+ emitted light at 489, 544, 588, and 622 nm. [ABSTRACT FROM AUTHOR]

The purpose of this study was to investigate the photoluminescence properties of Bi3+-activated Sr3B2O6. Pure Sr3B2O6 and Bi3+-doped Sr3B2O6 were synthesized by a solution combustion method. The phase and photoluminescence analyses of the borates that were synthesized were determined by using X-ray diffraction and a spectrofluorometer respectively at room temperature. It was observed that the synthesized Bi3+-doped Sr3B2O6 emitted blue light (441 nm) upon excitation with 366 nm. Finally, the Stokes shift of Sr3B2O6:Bi3+ was calculated and found to be 4646 cm–1.
