| 英文摘要 | A novel phosphor Gd4.67Si3O13:Tb3+, Ce3+ has been prepared by a high temperature solid-state method at 1350 degrees C for 6 h. X-ray diffraction (XRD), and Rietveld refinement is used to characterize crystal structure of as-synthesized phosphor. Upon 312 nm excitation, emission spectrum of Gd4.67Si3O13:0.02Tb(3+) shows a series of sharp peaks, corresponding to the 4f-4f transition of Tb3+. Monitoring 544-nm emission, photoluminescence excitation (PLE) spectrum of Gd4.67Si3O13:0.02Tb(3+) is composed of a 226-nm broad band and two sharp peaks (272 nm and 312 nm). Its critical doping content of Tb3+ is 5%. The absorption spectrum and emission spectrum of Gd4.67Si3O13:Ce3+ has broad bands due to the transition between the 4f(1) ground state and the 5d excited state. Ce3+ and Tb3+ co-doped phosphor samples have broad excitation range from 200 nm to 380 nm indicating it can be effectively excited by ultraviolet light, matching with the near-UV LED chips. By adjusting the ratio of Tb and Ce ions, color tunable phosphors from blue to green can be obtained. Chromaticity coordinates and thermal quenching properties are investigated in details. Its intensities decreased to 80% of the initial intensity (50 degrees C) at 150 degrees C and it does not decrease to half at 300 degrees C, indicating high thermal stability. All the results indicate that Gd-4.67Si3O13:Ce3+, Tb3+ phosphor have a potential application for near-UV LEDs. (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved. |
