Люминесцентные свойства боросиликатного стекла, легированного церием

ABS – BGP (Al2O3 – B2O3 – SiO2 – BaCO3 – Gd2O43 – P2O5) glasses doped with different Ce3+ concentrations were prepared by glass melting method. Optical, structural and luminescent properties have been characterized. Emission in the spectral range of 350–550 nm, associated with radiation transitions of Ce3+ ions was recorded. The luminescence decay kinetics is characterized by two components. The fast component is 45–90 ns. For the slow component, a decrease in the decay time from 4 to 0.9 us with increasing cerium ion concentration is shown. Based on the luminescence spectra, an assumption about the existence of various emitting states of the Ce3 + ion in borosilicate glass was made.
