Strontium aluminate based luminophors obtained using sol-gel method

The sol-gel method synthesized phosphors based on strontium aluminates activated with europium and dysprosium ions. The effect of the ratio of strontium and aluminum oxides on the crystallization and luminescent properties of the obtained luminophores has been investigated. It is shown that the dispersion of luminophore powders is 3 - 4 microns. In this case, in contrast to the traditional method of solid-phase sintering, the stage of grinding materials can be excluded.
