  • Ultraviolet (UVA)-emissive BaSiO3:Ce3+ phosphor was astonishingly reproducible by vacuum-sintering at a high temperature through a simple solid-state reaction method. It was conveniently formed in BaSiO3 phases. The compound showed the UVA emission and the UV-VUV excitation due to 5d-4f transitions from Ce3+ ions: emission peak at 380 nm with a 56 nm width. Its temperature dependence and vacuum UV excitability were examined for practical application as an excimer discharge lamp, which showed the high thermal stability (80% at 100℃) and the strong VUV excitations at 145 nm and 172 nm.
