摘要:
AbstractThe shift of the K‐absorption edge (δEk) was measured in Se100‐xInxbinary system where 0 ≤x≤ 30. The K‐edge of Se progressively shifted toward the lower energy side as the In concentration increased from 0 to 15 at.‐%. However, at higher concentrations, the relative shift started to decrease. The results are in accordance with Pauling's concept of electronegativity and indicate that the nature of the bonds is iono‐covalent in these glasses, as found in many crystalline solids. The composition dependence of the edge shift is also discussed in terms of the s
