Abstract:
Emission and excitation spectra and luminescence decay times of the SrS:Sb 3+ and SrSe:Sb 3+ powder phosphors are studied over the temperature range from 2 to 372 K. The emission band at 293 K is located at 600 nm for SrS:Sb 2 S 3 (0.05 mol%) and at 633 nm for SrSe:Sb 2 S 3 (0.2 mol%). The excitation processes are attributed to three transitions; (i) the intraionic transitions within Sb 3+ , (ii) the charge transfer transition from the host anion to Sb 3+ and (iii) the fundamental absorption by host crystal, followed by the transfer of the excitation energy to an unexcited Sb 3+ ion. The shape of the excitation spectrum of the intraionic transitions is similar to those of the absorption spectra of Tl + -type ions in alkali halides. The results are compared with those of MgS:Sb 3+ , CaS:Sb 3+ , CaSe:Sb 3+ and SrS:Bi 3+ .
