Abstract
In present work Mn2+-doped MgO-Al2O3-ZrO2-SiO2 materials were synthesized. Their structure, morphology, chemical composition and luminescent properties were studied using X-Ray diffraction, scanning electron microscopy, EDX analysis and luminecent spectroscopy. It was shown that the application of sol-gel method provides the high-volume homogeneity of chemical composition of synthesized materials. Introduction of Mn into the composition of sol-gel materials accelerates significantly the crystalization processes during the thermal treatment. In the luminescence spectra several groups of emission bands are observed. These bands are situated in blue and yellow-red part of spectrum. this phenomenon is related with incorporation of Mn2+ into the structure of different crystals formed during the thermal treatment of gels. Obtained materials can be perspective for application as luminophores in the lighting for plant production.
