Na/sub 4/Nb(PO/sub 4/)/sub 3/, a material with a reversible crystal-glass transformation: structural and optical comparison
Journal Article
·
· J. Solid State Chem.; (United States)
The phosphate Na/sub 4/Nb(PO/sub 4/)/sub 3/ exhibits a reversible crystal-phase change. Raman and optical investigations give evidence of the similarity between the covalent skeleton of the Nasicon-like crystalline phosphate and the network of the glass. Both types of materials contain octahedral NbO/sub 6/ groups with various Nb-O lengths. It is shown for the neodymium-doped glasses that these structural features induce a strong self concentration quenching of the Nd/sup 3 +/ emission.
