| 英文摘要 | a series of eu2+ and mn2+ activated novel sr3gdna(po4)(3)f phosphors have been prepared through a high temperature solid state reaction. the investigation revealed that sr3gdna(po4)(3)f crystallized in a hexagonal crystal system with the space group p (3) over bar (no. 147). the eu2+ activated phosphors can be efficiently excited in the range of 250 to 420 nm, which matches well with the commercial n-uv led chips, and give intense blue emission centering at 470 nm. by codoping the eu2+ and mn2+ ions into the sgnpf host and singly varying the doping content of the mn2+ ion, tunable colors from blue to white and then to yellow are obtained in sgnpf: eu2+, mn2+ phosphors under the irradiation of 390 nm. the energy transfer from the eu2+ to mn2+ ions is demonstrated to be a dipole-quadrupole mechanism in terms of the experimental results and analysis of photoluminescence spectra and decay curves of the phosphors. the critical distance between the eu2+ and mn2+ ions in sgnpf: eu2+, mn2+ was determined by the spectral overlap method. the investigation indicates that our prepared samples might have potential application in wleds. |
