α-Zn 2 SiO 4:Mn 2+ green emitting-phosphor was prepared by a high–energy planetaryball millingand post-annealing method. The effect of Mn 2+ doping concentration and annealing temperature on optical properties of the phosphors were systematically investigated by using XRD, FESEM, FTIR, Raman, Photoluminescence (PL) and Thermoluminescence (TL) spectroscopy.
