Synthesis of yellow and green phosphors based on zinc orthosilicate doped by manganese at low temperature by impregnation – coprecipitation method

The highest luminescence product consists of spheroidal and relatively uniform particles with sizes around 0.6-1.0 µm. The variation of the precipitated precursor with temperature, the influence of sintering temperature on structure and luminescence, the mineralization role of boric acid and the chemical reactions that occur with generation of precipitated precursors and upon heating to give luminescent solid solution products are mentioned.
