Fig. 5: Luminescent performances of CsCdCl₃:x%Sn.

a Normalized PL spectra of CsCdCl₃:10%Sn based on prompt and delayed (t_d = 1 ms) patterns under 254 nm or 282 nm excitation, along with the corresponding normalized PLE spectra. Afterglow decay curve of CsCdCl₃:x%Sn with the detected emission wavelength b 595 nm and c 565 nm. Pseudo color map of time-resolved PL spectra of afterglow for CsCdCl₃:10%Sn under d 254 nm and e 282 nm flash lamp. f The PLQY of CsCdCl₃:x%Sn. g TL spectra of CsCdCl₃:x%Sn. Excitation-prompt mapping of CsCdCl₃:10%Sn under h 97 K and (i) 297 K. Note: Due to limited space of the picture, only the excitation wavelengths of the start and end are shown. The color gradient of curves in Fig. 4h from left to right and in Fig. 4i from right to left solely represents the change in emission peaks based on the relevant excitation wavelength (ex: 250, 255, 260, 265, 270, 275, 280, 285, 290, 295, 300, 305, 310 and 315 nm, respectively), without any additional connotations.
