Abstract
2ZnO+SiO2+Xmol% TiO2 (Zn2SiO4-X-TiO2, 1≤X≤3) and 2ZnO+SiO2+3mol% MnO2 (Zn2SiO4-3-TiO2) compositions were prepared using nanoscale ZnO, SiO2, TiO2, and MnO2 particles. The mixing powders were calcined between 1000°C and 1300°C in a N2 atmosphere. Zn2SiO4 was the only phase in the calcined Zn2SiO4-X-TiO2 phosphors. We found that the photoluminescence (PL) properties of synthesized Zn2SiO4-X-TiO2 phosphors revealed these to be blue rather than green. The effects of TiO2 content and calcining temperature on the PL properties of Zn2SiO4-X-TiO2 phosphors were rigorously investigated.
