Luminescent properties of borosilicate glass doped with cerium

ABS–BGP glasses (Al$_{2}$O$_3$–B$_{2}$O$_3$–SiO$_2$–BaCO$_3$–Gd$_{2}$O$_3$–P$_{2}$O$_{5}$) doped with different concentrations of Ce$^{3+}$ 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 $\mu$s is observed with increasing cerium ion concentration. Based on the obtained results, it is assumed that Ce$^{3+}$ ions exist in different emission states in the borosilicate glass.
