Doping a small amount of cerium into quartz glass can block ultraviolet, mainly absorbing all ultraviolet to maintain maximum light transmission within the visible spectrum range.
Cerium doped quartz glass is used for solid-state laser pumping xenon lamps, solid-state laser filter, and other laser light source materials.
