(a) Luminescence decay kinetics for 225 nm emission of BaF2:Y, excited by a λexc = 22.8 eV (56 nm) synchrotron pulse (blue curve) and by pulsed CL of BaF2:Y (red curve); luminescence decay kinetics of 520 nm emission in CsPbBr3 nanocrystals under VUV excitations (green curve) and the IRF of the MCP-PMT detector (light-blue curve with shaded area). The iterative reconvolution biexponential fit results are presented as black curves for CsPbBr3 and BaF2:Y, excited by the synchrotron pulse. (b) Time-resolved emission spectra of a BaF2 crystal excited by 22.14 eV photons at 295 K.
