The composition-dependent microstructural morphology variations of Se₈₉Zn₂Te₅In₄ and Se₈₇Zn₂Te₅In₆ chalcogenide alloys are investigated. Glassy and nanophase surfaces and structural morphologies of these alloys have been described with help of scanning electron microscope (SEM) and transmission electron microscope (TEM), and their elemental concentrations are confirmed from the energy dispersive X-ray spectroscopy (EDX). Experimental results demonstrate that the microstructure of Se₈₉Zn₂Te₅In₄ alloy belongs to pure glassy state, while the Se87Zn2Te5In6 alloy is with nanophase structure.
