Abstract
In the present work, we have prepared high yield of glassy Se98Cd2 nanorods using melt–quench technique. The morphology and micro-structural analysis of as-prepared nanorods are characterized by SEM, XRD and EDX techniques. The glass transition and crystallization kinetics of glassy Se98Cd2 nanorods are studied at different heating rates (5, 10, 15, 20 K/min) using differential scanning calorimetric (DSC) technique. Four iso-conversional methods [Kissinger–Akahira–Sunose (KAS), Flynn–Wall–Ozawa (FWO), Tang and Straink] were used to determine the various kinetic parameters (crystallization temperature Tαc, transition temperature Tαg, activation energy of crystallization Eαc, activation energy of glass transition Eαg, order parameter n) of glass transition and crystallization process in non-isothermal mode. The monotonous decrease in activation energy Eα with the crystallization fraction α confirm the complex kinetic mechanism of the glassy Se98Cd2 nanorods.
