- Abstract
A series of LiSrBO:Ce, Tb phosphors have been prepared via a high-temperature solid-state reaction process. X-ray diffraction (XRD), scanning electric microscopy (SEM), photoluminescence (PL) spectra, and the diffuse reflection spectra were utilized to characterize the samples. The luminescence properties of LiSrBO:Ce, Tb phosphors have been discussed. The energy transfer process from Ce to Tb has been demonstrated to be a resonant type via the dipole-dipole interaction mechanism. The emissive colors of LiSrBO:Ce, Tb samples can be adjusted from blue to yellowish-green by the energy transfer of Ce and Tb, respectively. The results suggest the present phosphors can be potentially applied as a candidate of green-light phosphor for UV-pumped W-LED.
