英文摘要	In this work, the crystal structure and electronic structure as well as the synchrotron radiation vacuum ultraviolet-ultraviolet-visible (vuv-uv-vis) luminescence properties of li6y(bo3)(3) (lybo):ce3+ phosphors were investigated in detail. the rietveld refinement and dft calculation reveal the p2(1)/c monoclinic crystal phase and the direct band gap of the lybo compound, respectively. only one kind of ce3+ 4f-5d transition is resolved in terms of the low temperature vuv-uv excitation, uv-vis emission spectra and luminescence decay curves. furthermore, by constructing the vacuum referred binding energy (vrbe) scheme and applying the frequency-degenerate vibrational model, the impacts of 5d electron binding energy and electron-phonon coupling on luminescence of ce3+ in lybo are analysed. the results show that the ce3+ emission in lybo possesses a moderate intrinsic thermal stability. with the increase in concentration, the thermal stability of the emission gets worse due to the possible thermally-activated concentration quenching. in addition, the simulation of ce3+ emission profile at low temperature reveals that the 4f-5d electronic transitions of ce3+ ions can be treated to couple with one frequency-degenerate vibrational mode having the effective phonon energy of approximate to 257 cm(-1) with the corresponding huang-rhys parameter of approximate to 6, which indicates a strong electron-phonon interaction of ce3+ luminescence in the li6y(bo3)(3) host. finally, the x-ray excited luminescence spectrum of the lybo:5%ce3+ phosphor is measured to check the potential scintillator applications.
