In this work, we investigate the photoluminescence (PL) and the optically stimulated luminescence (OSL) of the SrS:Ce,Sm phosphor by means of time-resolved spectroscopy with excitation laser pulses of 2 ps duration. By comparing the PL measurements obtained with direct UV excitation and the OSL experiments performed using infrared wavelength, it was possible to measure a charge conversion lifetime of about 2.5±1 ns. A luminescence lifetime of 36±1 ns has also been found. These measurements are presented and discussed in connection with applications where the speed of the SrS:Ce,Sm luminescence is a crucial parameter %G English %L hal-00327469 %U https://hal.science/hal-00327469 %~ CNRS %~ UNIV-MONTP2 %~ IES %~ GES %~ MIPS %~ UNIV-MONTPELLIER %~ UM1-UM2 %~ UM-2015-2021
