Abstract
- Abstract: 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 0.04mol, respectively. Finally, the relation between the photoluminescence properties of Sm3+ and host compositions was discussed in detail. [Copyright &y& Elsevier]
