RED LUMINESCENCE PROPERTIES OF Pr³⁺-DOPED MSr₄(BO₃)₃ (M = Li, Na)

Pr³⁺-doped MSr₄(BO₃)₃ (M = Li, Na) were synthesized and determined by a combustion method and by X-ray powder diffraction analysis. The photoluminescence (PL) behavior of the borates that were prepared was investigated by using a fluorescence spectrometer. The emission peaks of the Pr³⁺-doped MSr₄(BO₃)₃ (M = Li, Na) were observed at 609 and 606 nm, respectively. Finally, the PL spectra of LiSr₄(BO₃)₃:Pr³⁺ and NaSr₄(BO3)₃:Pr³⁺ with different Pr³⁺ doping concentrations were analyzed in detail.
