LUMINOPHORES BASED ON STRONTIUM ALUMINATES PRODUCED BY THE SOL-GEL METHOD

摘要

Luminophores based on strontium aluminates activated by europium and dysprosium ions are synthesized using the sold-gel method. The effect of a ratio between strontium and aluminum ions on crystallization and luminescent properties of the luminophores produced is investigated. It is demonstrated that the degree of dispersion of luminophores powders is 3-4 mu m. In contrast to the traditional solid-sintering method, the stage of milling materials can be eliminated.
