Paper Abstract

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 characterization 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.
