The authors investigate the structural change of a ZnO-P2O 5 sintered matrix for the preparation of SnO-doped zinc phosphate (SZP) glass using a platinum crucible. Heat treatment of zinc oxide and ammonium phosphate at 800 °C causes the formation of a Zn2P 2O7-like species, which is effective in preventing damage to the platinum crucible. Although the thermal property of the glass was affected by added Al2O3, Al2O3 hardly affects the quantum efficiency of the SZP glass phosphor. This process is important for the fabrication of contamination-free phosphate glass using ammonium phosphate as a starting material.
