摘要: Chlorides of NH4Cl and SrCl2 fluorides AlF3 SrF2 were added to raw materials acting as the flux for preparing SrSi2O2N2:Eu2+ phosphor. The effects fluxes on phase formation, particle morphology, size, photoluminescence properties investigated. results revealed that morphology intensity largely dominated by type material its adding amount. chloride-based was found favor formation phase. Among fluxes, sample with presented narrow distribution cleaner surface, enhanced emission an increased external quantum efficiency 68% 22%, respectively, compared those without any
