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.

具有全波段紫外线屏蔽能力的高透明铈掺杂玻璃

随着臭氧层的变薄，已经相当注意开发能阻止或减少紫外线（UV）透射的材料。在这里，使用熔融淬火法成功地制造了具有较高透明度的大块掺铈玻璃。可以通过光致发光激发的光学性质，发射光谱，衰减曲线和吸收光谱来推断玻璃中Ce ³⁺和Ce ⁴⁺的变化比例。这些玻璃由于吸收了Ce ³⁺和Ce ⁴⁺而具有出色的紫外线阻隔能力。在高温，长期紫外线辐射，强碱溶液和丙酮的条件下，已证明它们具有出色的物理和化学稳定性。因此，我们的掺铈玻璃在紫外线防护设备中可能具有吸引力。
