Carrying out crystallization studies for both Se0.95In0.05 and Se0.90In0.10 chalcogenide glasses under non-isothermal conditions at different heating rates, it was realized that a rate controlling process occurs where random nucleation of one- to two-dimensional growth is accompanied with the introduction of up to 10 at% In into glassy Se matrix. The crystallization kinetics together with its dimensionality has been studied using the four currently used isoconversional models (Kissinger-Akahira-Sunose, Ozawa-Flynn-Wall, Tang, and Starink). The activation energy of crystallization (E (c)) has been determined using these indicated four models where a satisfactory concurrence is achieved. The value of E (c) shows a decrease while increasing both the In-content as well as the extent of crystallization.
