Abstract
- Abstract: In this paper, we reported a series of halosilicate photoluminescence (PL) materials, which have the chemical composition Ba5SiO4(F x Cl6−x ):0.05Eu2+ (x =0, 1, 3, 4, 6). It is found that, under 365-nm UV light, Ba5SiO4Cl6:Eu2+ phosphor exhibits strong blue light with peak wavelength at 442 nm. By adding small amount of F− to the host lattice for the substitution of Cl−, the emission wavelength of the Ba5SiO4(F, Cl)6:Eu2+ phosphor changes to 503 nm, corresponding to the green light. The possible luminescence mechanism in this phosphor system was also discussed. [Copyright &y& Elsevier]
