Synthesis and characterization of Zn_2SiO_4:Mn~(2+) Nanophosphors Prepared from different Zn source in liquid precursor by Flame Spray Pyrolysis

摘要

Zn_2SiO_4:Mn~(2+) nanophosphors were synthesized by flame spray pyrolysis (FSP) from different liquid precursors. Luminescence and crystalline properties were investigated as different Zn-source materials in aqueous precursor. Mn-doped zinc silicate (Zn_2SiO_4:Mn~(2+)) crystalline structures were annealed low temperature of 1000°C for 1hr. The emission peak was found at 525nm for green emitting phosphor. The influence of different experimental conditions such as liquid precursor from different Zn-source and annealing temperature on both crystallinity and the luminescence properties of Zn_2SiO_4:Mn~(2+) nanophosphors were investigated.
