Highly transparent cerium doped glasses with full‐band UV‐shielding capacity

With thinning of the ozone layer, considerable attention has been paid to developing materials that block or reduce ultraviolet (UV) transmission. Here, bulk cerium doped glasses with relatively high transparency were successfully manufactured using the melt‐quenching method. The varied ratio of Ce3+ and Ce4+ in glasses could be deduced by optical properties in photoluminescence excitation, emission spectra, decay curves and absorption spectra. These glasses exhibit excellent UV‐blocking capacity due to the absorption of Ce3+ and Ce4+. Their outstanding physical and chemical stability have been demonstrated in the condition of high temperature, long‐term UV radiation, strong alkali solution and acetone. Hence, our cerium doped glasses are potentially attractive candidates in UV‐shielding device.
