Glass-Ceramics with CaF2 as their Crystalline Phase

1 Glass-Ceramics with CaF2 as their Crystalline Phase 

These glass-ceramics have commonly been doped with Eu, Nd and Er. In the case of time-resolved spectroscopic studies have shown that Eu ions are at least partially incorporated inside the CaE2 crystallites. Similarly, Er + ions are incorporated in the crystallites, forming a solid solution Cai xErxF2+x- However, the incorporation of Nd in the Cap2 crystallites seems weaker [23].
