Photoluminescence properties of M2Mg(BO3)2:Sm3+ (M:Sr and Ba)

M2Mg(BO3)2:Sm3+ (M:Sr and Ba) phosphors were synthesized by a solution combustion synthesis method followed by heating of the precursor combustion ash at 900 °C in air. The synthesized materials were characterized by using the powder XRD. The emission and excitation spectra of these materials were measured at room temperature with a spectrofluorometer. Both Sr2Mg(BO3)2:Sm3+ and Ba2Mg(BO3)2:Sm3+ phosphors emit a strong in orange-red region. It was observed that the optimum concentration of Sm3+ in Sr2Mg(BO3)2 and Ba2Mg(BO3)2 are 0.01 and 0.04 mol, respectively. Finally, the relation between the photoluminescence properties of Sm3+ and host compositions was discussed in detail.
