| The X-ray Ge K absorption (emission) bands were measured in the stoichiometric glass system (GeS2)x(Bi2S3)1-x (x = 0 ÷ 0.5) and in the Ge20BiySe80-y system (y = 0, 7 and 13). The results do not confirm the existence of the Ge-Bi bond and they imply that the GeS2-clusters are formed in both studied systems. |
