CsCeSiS4 thiosilicate single crystals were obtained by high-temperature flux synthesis. The absorption spectrum in the region of 450 nm is formed by f-> d transitions in the Ce3+ ion. The nonelementary 5d-> 4f band of Ce3+ ion emission is observed in the photo- and X-ray excited luminescence spectra in the region of 520 nm at temperatures of 5-330 K. The inertialess luminescence decay kinetics upon excitation by X-ray synchrotron radiation is characterized by a dominant component with a decay time tau=0.88 ns. The luminescence of Ce3+ ions is efficiently excited by the intracenter way or due to the recombination of band charge carriers. Keywords: Ce3+ ion, luminescence decay kinetics, interconfigurational transitions, synchrotron radiation.
