A special metal oxide glass created by researchers in China can help protect living cells by absorbing and blocking damaging ultraviolet rays. It could be used in several applications, including as a protective shield for electronic instruments in space. The researchers used a metal oxide – cerium (IV) oxide (CeO2) – well-known for its ability to absorb UV photons to craft the composite glass-based UV absorber.
Other key features of the final composite material are optical transparency of the glass and ability to suppress the separation of photo-generated electrons and holes...
