Abstract:

We investigated the room temperature photoluminescence of calcium thiogallate codoped with Ce and Pr. Line shaped emissions superimposed over a wide and composed luminescence band were observed. Different components were distinguished by means of time resolved photoluminescence measurements, and were attributed to the dopant species. A band at 2.24 eV, not previously reported, was observed.
