On The Synthesis Of Manganese Activated Zinc Silicate Phosphor

Manganese activated zinc silicate is a classical phosphor with large applications in optoelectronic device manufacture. Some aspects concerning the influence of precursor quality on Zn2SiO4:Mn phosphor formation and properties are presented. Phosphor samples were prepared by classical ceramic technique from homogeneous mixtures consisting from MnCO3 and various sorts Of SiO2 and ZnO-sources. The precursors and phosphor characterisation was achieved by thermal analysis, surface area measurements, IR spectroscopy, X-ray diffraction and fluorescence spectroscopy. The quality and reactivity of precursors influence Zn2SiO4: Mn phosphor formation rate thus conducting to materials with different structural and luminescence characteristics.
