| 摘 要： | A novel white light emitting long-lasting phosphor Cd1-xDyxSiO3 is reported in this letterThe Dy^3 doped CdSiO3 phosphor emits white light. The phosphorescence can be seen with the naked eye in the dark clearly even after the 254nm UV irradiation have been removed for about 30min. In the emission spectrum of 5% Dy^3 doped CdSiO3 phosphor, there are two emission peaks of Dy^3 , 580nm (^4F9/2→^6H13/2) and 486nm (^4F9/2→^6H15/2), as well as a broad band emission located at about 410nm. All the three emissions form a white light with CIE chromaticity coordinates x=0.3874, y=0.3760 and the color temperature is 4000 K under 254 nm excitation. It indicated that this phosphor is a promising new luminescent material for practice application.

| Abstract: | A novel white light emitting long-lasting phosphor Cd1-xDyxSiO3 is reported in this letter. The Dy3+ doped CdSiO3 phosphor emits white light. The phosphorescence can be seen with the naked eye in the dark clearly even after the 254 nm UV irradiation have been removed for about 30 min. In the emission spectrum of 5% Dy3+ doped CdSiO3 phosphor, there are two emission peaks of Dy3+, 580 nm (4F9/26H13/2) and 486 nm (4F9/26H15/2), as well as a broad band emission located at about 410 nm. All the three emissions form a white light with CIE chromaticity coordinates x=0.3874, y=0.3760 and the color temperature is 4000 K under 254 nm excitation. It indicated that this phosphor is a promising new luminescent material for practice application. |
