| 英文摘要 | The luminescent properties of Pr3+-doped LaB3O6, SrAl12O19, SrB4O7 and NaYF4 in the vaccum ultraviolet (VUV) range at different temperatures were investigated under the excitation of high-energetic synchrotron radiation. For Pr3+ ions in LaB3O6, SrAl12O19 and SrB4O7, only the parity-forbidden S-1(0)-> 4f(2) transitions were observed in the emission spectra at relatively low temperature; but the parity-allowed 4f 5d -> 4f(2) transitions appeared simultaneously when the temperature was high enough. And the intensity of broad 4f5d -> 4f(2) emission increased relative to the intensity of S-1(0)-> 4f(2) emissions with increasing temperature. Then the thermal equilibrium model of energy levels was employed to the lowest 4f5d state and S-1(0) state of Pr3+ in the three hosts. The calculated curves were in good agreement with the experimental values, indicating the occurrence of the thermal excitation from S-1(0) state to 4f 5d states at high temperatures when the lowest 4f 5d state lies higher than S-1(0) state and the photon energy is high enough. |
