摘要

Novel glass-ceramics with embedded thermoelectric Bi_2Se_3 crystals were prepared from glass matrices in the Ge_(20)Se_(100-x)Bi_x (x = 5, 10, 12 mol%) system. Based on DSC results performed at different heating rates, characteristic activation energies (E_e) and Avrami exponents (n) were obtained and analyzed by using Kissinger's relation, Ozawa's method, Augis-Bennett approximation and Matusita-Sakka theory. XRD results showed that pure Bi_2Se_3 crystalline phase precipitated upon annealing at different temperatures for various time. The crystal size and crystalline fraction in the samples could be tuned by controlling the annealing time.
