Abstract
We reported a single-phased CaScAlSiO6:Ce3+, Tb3+, Eu3+ as a potential full-color emitting phosphor for the application in fluorescent lamps. The CaScAlSiO6:Ce3+, Tb3+, Eu3+ phosphor exhibits three bands under 254Â nm excitation: one band situated at 380Â nm is attributed to the 5dâ4f transitions of Ce3+ ions, the second band with sharp lines peaked at 542Â nm is assigned to the 5D4â7FJ transitions of Tb3+ ions, the third band in the orange-red region (580-700Â nm) is originated from 5D0â7FJ transitions of Eu3+ ions. The Commission Internationale de I'Eclairage (CIE) chromaticity coordinates (0.30, 0.30) and high color rendering index (CRI=88) can be achieved upon excitation of 254Â nm light. It is suggested that CaScAlSiO6:Ce3+, Tb3+, Eu3+ can serve as a potential single-phased full-color emitting phosphor for phosphor-converted fluorescent lamps.
