| Abstract: | Gd2MoB2O9 doped with Sm3+ and Dy3+ were used for this study. The photoluminescence behaviors of Sm3+ and Dy3+ in this phosphor material were investigated by the excitation and emission spectra. The Sm3+-doped Gd2MoB2O9 phosphor powders show a red luminescence, whereas the Dy3+-doped Gd2MoB2O9 phosphor powders show a yellow luminescence. In addition, the optimum doping concentration and the time-resolved luminescence spectroscopy were also investigated. |
