Luminescent hybrid materials based on organic phosphors and fluorides in the PbF2-LaF3 system

Abstract

Powder hybrid materials based on 8-hydroxyquinolate lithium organic phosphor and - LaF3 inorganic fluoride matrix PbF2 have been synthesized. Hybrid materials were obtained by co-precipitation from aqueous-alcoholic solutions with ammonium fluoride under various conditions - different concentrations of precursor solutions, Pb/La ratio, and the siquensy of reagents’ mixing. All obtained hybrid materials showed effective broadband luminescence in the region of 390-500 nm. The photoluminescence intensity during reverse deposition was found to be higher than during direct deposition for different concentrations of reagents.
