摘要：

Sr1.995–1.5xGdxSi O4:0.005Eu2+ phosphor series with x=0–0.08 mol for near-ultraviolet white light-emitting diodes(NUV w-LEDs) were synthesized via solid-state reaction method. XRD profile pattern and refinement results demonstrated that doping Gd3+ions resulted in the phase transformation(β-Sr2 Si O4→α’-Sr2 Si O4). The photoluminescence spectrum of the sample with x=0 mol displayed two emission peaks centered at 470 and 525 nm. The two-peak spectra became one-peak spectra with the Gd3+ concentration increasing. Actually, the fitting results demonstrated that the one-peak spectra were still composed of two single emission spectra. The photoluminescence intensity was improved and the CIE chromaticity coordinates were adjusted via doping Gd3+.
