Luminescent Properties of Borosilicate Glass Doped with Cerium

Resumo

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.
