Luminescent Properties of Borosilicate Glass Doped with Cerium

ABS–BGP glasses (Al2O3–B2O3–SiO2–BaCO3–Gd2O3–P2O5) doped with different concentrations of Ce3+ ions are synthesized by the high-temperature melting technique. Optical, structural, and luminescence properties were studied. Emission connected with the transitions of Ce3+ ions is recorded in a spectral region of 350–550 nm. The luminescence decay kinetics is characterized by two components: fast and slow. The fast decay component is 45–90 ns; decreasing decay time of the slow component from 4 to 0.9 μs is observed with increasing cerium ion concentration. Based on the obtained results, it is assumed that Ce3+ ions exist in different emission states in the borosilicate glass.
