AbstractPhotoluminescence properties of Ce-doped Sr3Al2O5Cl2 crystals prepared by a solid-state reaction method are first investigated with excitation energies in the vacuum-ultraviolet (VUV) to ultraviolet (UV) range. Six bands are observed in the excitation spectrum of the Ce3+ 5d -> 4f emission at 15 K. The highest energy band is attributed to the host excitonic absorption, from which the band gap energy of the host is estimated to be around 7.2 eV. The four lowest energy bands are assigned to the 4f(1) -> 5d(1-4) transitions of Ce3+ located on the three distinct Sr2+ sites in Sr3Al2O5Cl2 with almost equal probability, based on a comparison between excitation band maxima energies and 4f -> 5d transition energies obtained from wave-function-based CASSCF/CASPT2 calculations with spinorbit coupling on Ce-centered embedded clusters. The 4f1 -> 5d(5) transition, not observed in the low-temperature excitation spectrum, is found to be overshadowed by a nearby defect-related excitonic absorption. On the basis of present experimental and calculated results for Ce-doped Sr3Al2O5Cl2, the energy-level diagram for the 4f ground states and the lowest 5d states of all trivalent and divalent lanthanide ions on the Sr2+ sites of Sr3Al2O5Cl2 is constructed and discussed in association with experimental findings.
