| Abstract: | The influence of fluoride on the luminescence of LiEuM2O8 (M=Mo, W) was studied. LiEuMo2O8 and LiEuW2O8 formed the whole range of solid solutions, which emitted intense red luminescence under the excitations by 395, 465 and 535 nm wavelengths. When doped with fluoride, the materials also formed solid solutions and the luminescent intensity was remarkably enhanced. The phosphor with optimized compositions in this system would be a promising red component for solid-state lighting devices based on GaN light-emitting diodes. |
