摘要：
Photoluminescence and excitation spectra, luminescence decay curves, and time-resolved photoluminescence spectra are observed for CaS:Eu,Na powder phosphors at various temperatures between 10 and 297 K. The detailed spectra of the Eu3+ center in CaS are observed for the first time. The emission lines due to the Eu3+ center are classified into two groups originating from centers A and B. The A center is attributed to the isolated Eu3+ center, whereas the B center, to the paired Eu3+-Eu2+ center.
