Synthesis of Mn-doped Zn2SiO4 phosphor particles by solid-state method at relatively low temperature and their photoluminescence characteristics

Mn-doped Zn2SiO4 phosphor particles having submicrometer sizes were synthesized by a solid-state reaction method using methyl hydrogen polysiloxane-treated ZnO, fumed SiO2 and various Mn sources. The crystallization and photoluminescent properties of the phosphor particles were investigated by X-ray diffraction(XRD), scanning electron microscope(SEM), and by their photoluminescence(PL) spectra. Due to the effect of the dispersion and coherence of the methyl hydrogen polysiloxane-treated ZnO, the Mn-doped Zn2SiO4 particles were successfully obtained by a solid state method at 1000℃, and the maximum PL intensity of the prepared particles under vacuum ultra violet(VUV) excitation occurred at a Mn concentration of 0.02mol and a sintering temperature of 1000℃.
