Figure 5
(a) Normalized time-resolved emission spectra of a BaF2 crystal excited by 22.14 eV photons at 295 K, integrated in the time window of Δt = 400 ps with δt = 0 ns delay with respect to the excitation pulse (1) and in the time window of Δt = 160 ns with δt = 10 ns delay (2). (b) Reflectance (blue line with shaded area) and excitation (black line) spectra for the 225 nm cross-luminescence of the BaF2 crystal at 15 K. |
