| 英文摘要 | The host structure and the sync-hrotron radiation VUV-UV luminescence properties of samples BaMg2Si2O7 (BMSO):Ln (Ce3+, Eu2+) at different doping levels and different temperatures were investigated in detail. Three important aspects are studied to elucidate the luminescence properties of samples: (1) the vacuum referred binding energy (VRBE) scheme is constructed with the electron binding in the BMSO host bands and in the Ce3+ and Eu2+ impurity levels with the aim to explain the different thermal stabilities of Ce3+ and Eu2+ emissions; (2) the electron-vibrational interaction analysis on the narrow Eu2+ emission indicates a weak electron-phonon interaction in the current case; (3) by using three models (Inokuti-Hirayama, Yokota-Tanimoto, and Burshtein models) at different conditions, the energy transfer dynamics between Ce3+ and Eu2+ was analyzed. It reveals that the energy transfer from Ce3+ to Eu2+ via electric dipole-dipole (EDD) interaction is dominant while energy migration between Ce3+ is negligible. Finally, the X-ray excited luminescence spectra of samples BMSO:Ce3+/Eu2+ are collected to evaluate their possible scintillator applications. |
