Abstract:

Five bismuth compounds with the cubic sillenite structure I23, Bi12SiO20, Bi12GeO20, Bi12TiO2, Bi12ZnO19 and Bi12PbO19 were synthesized. Infrared and Raman spectra of these compounds and of Bi2O3 with and without NO were measured. It is shown that fundamental mode frequencies in these covalent oxides are surprisingly high and that hope for an oxide window material has become vanishingly small.
