| 摘 要： | The luminescent properties of Pr3+-doped LaB3O6, SrAl12O19, SrB4O7 and NaYF4 in the vaccum ultraviol-et (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 1S0→4f2 transitions were observ-ed in the emission spectra at relatively low temperature; but the parity-allowed 4f5d→4f2 transitions appeared simultaneously when the temperature was high enough. And the intensity of broad 4f5d→4f2 emission increased relative to the intensity of 1S0→4f2 emissions with increasing temperature. Then the thermal equilibrium model of energy levels was employed to the lowest 4f5d state and 1S0 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 1S0 state to 4f5d states at high temperatures when the lowest 4f5d state lies higher than 1S0 state and the photon energy is high enough. |
