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.
