“…[20] Glass-ceramics are usually prepared from the matrix glasses by controlling the crystallization behavior. [21,22] However, the target crystal can only be precipitated in a specific glass composition, which limits the choice of glass composition. Generally, the refractive index of the precipitated crystal phase is very different from that of the remaining glass phase, which will increase the Rayleigh scattering coefficient.…”

We reported an ultrabroadband mid-infrared (MIR) emission in the range of 1800 nm–3100 nm at room temperature (RT) from a Cr2+:ZnSe-doped chalcogenide glasses (ChGs) and studied the emission-dependent properties on the doping methods. A series of Cr2+:ZnSe/As40S57Se3 (in unit wt.%) glass-ceramics were prepared by hot uniaxial pressing (HUP) and melt-quenching methods, respectively. The glass-ceramics with MIR emission bands greater than 1000 nm were successfully prepared by both methods. The effects of matrix glass composition and grain doping concentration on the optical properties of the samples were studied. The occurrence state, morphology of the grains, and the microscopic elemental distributions were characterized using x-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive spectrometer (EDS) analyses.

et al.. Performance modification of third-order optical nonlinearity of chalcogenide glasses by nanocrystallization. Ceramics International, Elsevier, 2019, 45 (15), pp. Abstract:We demonstrate the modification of the third-order optical nonlinearity (TONL) of chalcogenide glasses (within the GeS 2 -In 2 S 3 -CsCl ternary system) by nanocrystallization, i.e., by controlling the precipitation of nanocrystals (in pure In 2 S 3 phase) within the amorphous background. Compared with the parent glass, the resultant chalcogenide glass ceramics (ChGCs) have unchanged infrared transmittance but modifiable optical bandgap energy with treatment duration. Both nonlinear refraction coefficient and nonlinear absorption coefficient of the ChGCs are increased due to the appearance of In 2 S 3 nanocrystals. ChGCs subjected to heat treatment for 1.3-2 h are found to exhibit the optimum TONL performance.
