Knowledge of endothermic and exothermic heat capacities of optoelectrics materials is important to define their energy/data storage capability. Heat capacities of Se98-xZn2Inx (0 ≤ x ≤ 10) chalcogenide glasses at glass transitions (Tg) and crystallisations temperatures (Tc) have been reported in this work. The evaluated endothermic (ΔCpg) and exothermic (ΔCpc) heat capacities of Se98-xZn2Inx system varies with alloying concentrations obtained minimum and maximum respectively at threshold composition (6 at wt.% of In). The up and down trend in ΔCpc and ΔCpg at Tg, Tc could be explained on the basis of structural units/avarage coordination number 〈r〉 of the glassy materials.
