Popis: NaBaPO4:Eu and ZnAl2O4:Eu phosphors with different dopant content were prepared by solution-combustion (SC) and sol-gel (SG) method. SC route gives samples with high crystallinity, that does not always leads to increase in luminescent properties due to formation of admixture phases. In NaBaPO4 phosphor series, crystallite size reversly depends on admixture Ba3(PO4)2 phase content. Increase in europium concentration up to 10% lead to decrease of crystallite size in samples prepared by SC method, but increase of crystallite size in samples prepared by SG method. For ZnAl2O4:Eu, prepared by sol-gel technique, increase in Eu concentration leads to amorphization of structure.
