The purpose of this work is to study the effect of some precipitation conditions on the luminescent properties of manganese-doped zinc silicate when synthesized in a new approach - impregnated precipitation method. The samples are characterized by thermal analysis, infrared IR, luminescent spectrum (PL), X-ray diffraction spectrum and scanning electron microscope (SEM). The results showed that manganese - doped zinc silicate luminescent material prepared by the impregnated precipitation method has higher luminescence than the traditional co-precipitation method. Samples with the highest luminescent properties were synthesized under the following conditions: concentration of Zn (CH3COO)2 is 1M, the precipitate aging time of 20 minutes, the washed filtered precipitate, impregnated with Mn2+ with a content of 1.5 % mol compared to the total metal, dried at 80 °C and then heat at 900 0C for 45 minutes. The obtained product is single-phase zinc silicate with composition of Zn1,97Mn0,03SiO4, rhombic structure with most particles varying in size of 0.3 - 0.5 µm, emitting green light with λmax = 525 nm when excited by UV rays with wavelength of 254 nm. Forming a single-phase Zn2SiO4 crystal at 900 0C for 45 minutes allowed to reduce the energy required for the sintering process compared with the solid - phase reaction method.
