英文摘要	A series of dy3+-doped sr2(1-y)ca2yy8(sio4)(6)o-2 (0 y 1) white phosphors were synthesized by the solid-state reaction. all samples crystallize into a hexagonal crystal system with space group p6(3)/m (176) by the determination of xrd rietveld refinements. with the change in ca/sr ratio, the crystal environment of active ions is lightly affected. upon excitation by uv/vuv/cathode ray sources, the samples present an efficient white light emission with significant differences in the blue/yellow ratio of dy3+ characteristic transitions. based on luminescence properties, decay times and thermal properties, the interesting phenomenon with excitation energy increasing from uv to electron beam can be reasonably explained by a potential mechanism we proposed. with the introduction of bi3+, the white emission intensity is rapidly enhanced and the optimal intensity reaches to 3.75 times compared with the single doped dy3+ sample. to evaluate the applicability of this phosphor, we packaged two light-emitting diode devices and measured the actual luminescence efficacies and cie chromaticity coordinates. these results indicate that the silicate phosphors have the potential for multifunctional application in ultraviolet-based light-emitting diodes, mercury-free lamps, and field-emission displays.
