Solarization resistant rare earth doped glasses

Abstract:

Substantially alkali free glasses are disclosed which can be used to produce substrates for flat panel display devices. The glasses can have a loading of fluorine and ceria to achieve exemplary solarization and UV protection attributes when exposed to UV radiation. Methods for producing substantially alkali free glasses using a float or downdraw process (e.g., a fusion downdraw process) are also disclosed.
