It has been investigated the photoluminescence and X-Ray diffraction spectra of ZnS : Mn microcrys-tals (dimension ~ 25 m). After mechanical crush (time 10 and 20 min) the physical properties of micro-crystals was changed. Dimension of micro micro-crystals decrease up to 10 m (mechanical crush 10 min) and 5 m (mechanical crush 20 min); intensity of photoluminescence decrease too at 6,5 and 10 times accord-ingly. The paper will present the physical reasons of this result.

Keywords: Mechanosynthesis, Zinc sulfide, Manganese impurity, Photoluminescence, EPR spectra, X-ray diffraction analysis, Surface morphology.
