Alkali metal insertion and dielectric studies on anion excess fluorite related mixed oxide Bi2Te2W3O16

Insertion of alkali metals like Li and Na into the tunnels of anion excess fluorite related complex mixed oxide Bi2Te2W3O16 using n-butyllithium and NaN3, respectively has been performed; the preliminary structural, Raman spectra, and electrical resistivity of the alkali metal inserted phases and the dielectric properties of Bi2Te2W3O16 are reported.
