“…This phenomenon can also be found elsewhere such as in Ref. [18,26,27] In this work, the data at the lower temperature were used to calculate E c . E c of the lower temperature crystallization peak (E p1 ) of the three samples are obtained using the Matusita-Sakka's method (MS) and listed in Table II.…”

Novel glass‐ceramics with embedded thermoelectric Bi2Se3 crystals were prepared from glass matrices in the Ge20Se100−xBix (x = 5, 10, 12 mol%) system. Based on DSC results performed at different heating rates, characteristic activation energies (Ec) 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 Bi2Se3 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.

“…It might be correlated with another possibility for the additional quenching mechanism. A more likely quenching mechanism is energy transfer to a vibrational impurity such as –OH or –SeH 27 . The Dy 6 H 13/2 levels are especially likely to be quenched by –OH, because the energy gap to the next lowest level matches the –OH vibrational energy of 3300 cm −1 very well.…”

In the present work, properties of Dy3+‐doped chalcogenide glasses as a stoichiometric formula of (0.9−x)GeSe2–xAsSe3/2–0.1GaSe3/2 (x=0.1, 0.2, 0.3, 0.4, 0.5, 0.6) were investigated as a comparison with the previously studied Ge–Ga–Se system. Property measurements include differential thermal analysis, density, Vis‐NIR and IR transmission spectra, and fluorescent emission spectra. Judd–Ofelt analysis was performed using the calculated oscillator strengths of glasses. All properties of glasses show obvious dependence on compositions. Especially, the improved devitrification resistance and the longer fluorescence life at 1.34 μm emission were observed with the increasing As content. Noticeably, abnormal changes in some properties occurred to the glass whose average coordination number corresponds to the threshold of two‐dimensional–three‐dimensional topological phase transition.

“…This could mean the saturation of nucleation sites in the final stage of crystallization, and similar phenomenon was also observed in early studies. 19,25,26 Activation energies of crystallization were obtained from the slope of these linear fittings as shown in Table III. Activation energies at different heating rates are slightly different with an average value of 165 kJ/mol.…”

Effects of Pb on thermal stability and crystallization kinetics of chalcogenide glasses (1−x)(0.85GeS2−0.15Sb2S3)−xPbS (x = 0–0.4) have been carried out by a detailed calorimetric study and structural analysis. The glass stability was assessed based on three criteria, while the activation energies of crystallization were calculated under nonisothermal crystallization conditions by the Kissinger method, the Augis/Bennett method, the Mahadevan method, and the modified Ozawa method, respectively. Both stability criteria and activation energies of crystallization suggest that the glasses possess excellent thermal stability. The thermal stability decreases with addition of PbS but is insensitive to the content of PbS in the range from x = 0.1 to 0.4. Raman, XRD, and molar volume structural characterization suggested that the excellent thermal stability of these glasses is due to the glass former role of PbS. The calculated Avrami exponent pointing to a 3‐dimensional crystallization mechanism which explains the reason for the previously reported successful preparation of infrared transmitting chalcogenide glass‐ceramics.
