Abstract
A process for the preparation of luminophore based on calcium-scandium silicate activated with cerium ions involves the preparation of the reaction mixture by mixing stoichiometric mixture of components: CaCO3, SC2O3, SiO2, CeO2, in ratio of Ca:Sc:Si:Ce 2.97:2:3:0.03 atomic fractions, in the presence of charge accumulator, annealing thereof in reducing medium. NaF is used as a charge accumulator which is added to the reaction mixture and subjected to annealing at a temperatureof 1300-1320 °C, and NaF is used in amount corresponding to the content of alcali metal 0.005-0.05 atomic fractions.
