Notes:
The shift of the K-absorption edge (ΔEk) was measured in ternary alloys of Ga30Se70-xInx (x = 0, 5, 10, 15, 20) with respect to the binary Ga30Se70 alloy. It was observed that the K-edge of selenium shifted progressively towards the lower energy side as the indium concentration increased from 0 to 10 at.%. However, at higher concentrations, the relative shift started to decrease. These results are in accordance with Pauling's concept of electronegativity and indicate that the nature of the bond 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 structure of the Se—Ga system.
