Effect of heat treatments on the luminescence properties of Zn2SiO4:Mn2+ phosphors prepared by glycothermal methods

► Glycothermal synthesis of α-Zn2SiO4:Mn2+. ► High photoluminescence property of α-Zn2SiO4:Mn2+ prepared by glycothermal method. ► XANES characterization of Mn species in α-Zn2SiO4 calcined at various temperatures. ► Highly homogeneous distribution of Mn2+ in the α-Zn2SiO4 host.
