Low-temperature synthesis of Zn2SiO4:Mn green photoluminescence phosphor

► Synthesis of Zn2SiO4:Mn by solid state sintering at a low temperature of 1000 °C in air. ► Dissociation of water of crystallization in silicic acid promote sintering efficiency. ► Photoluminescence efficiency comparable with that of the commercial phosphor. ► Enhancement in luminescence with MgCO3 co-doping and refiring as well as ZnO addition. ► XRD confirm single phase willemite structure (rhombohedral) of Zn2SiO4:Mn.
