英文摘要	A series of ln-doped ksrpo4 (ln = ce3+, eu3+, eu2+, pr3+) phosphors are prepared through a high-temperature solid-state method. the ksrpo4 compound is confirmed to possess a beta-k2so4 structure with the pnma group by rietveld refinement, and the temperature-dependent lattice parameters are investigated with the powder x-ray diffraction results at different temperatures. ce3+ and eu3+ ions are introduced to probe the crystal field strength (cfs) and the lanthanide site symmetry by using vuv-uv-vis spectroscopy. the temperature-dependent luminescence properties of ksrpo4: ce3+/eu2+ exhibit an excellent thermal stability of ce3+/eu2+ luminescence. based on the vuv-uv-vis spectra of ce3+ and eu3+ doped ksrpo4, the vacuum referred binding energy (vrbe) scheme is constructed to understand the redox properties of eu, the 5d energy levels of pr3+ and the thermal quenching characteristics of ce3+ and eu2+ luminescence.
