“…The values of n for direct allowed and direct forbidden transitions will be ½ and 3/2 respectively. For the indirect allowed and indirect forbidden transitions n can take values 2 and 3 respectively [32,42,43]. The band gap is determined for all the films from the plot of ( ) n 1 α versus photon energy ν h on the xaxis by extrapolating the linear portion of the graph to the 0 = ν h .…”

“…It was reported by several authors that the peak positions for the wurtzite or sphalerite phases of ZnS thin films shifted from the typical positions. This difference may be proceeding from the lattice expansion or distortion due to the new phases of impurities or intrinsic defects such as vacancies and interstitials [34][35][36][37][38][39]. It was shown in Fig.…”

“…This reveals that the temperature required for the formation of the hexagonal ZnS phase is reduced by using ZnS nanopowders. 31,32 Therefore, it can be suggested that ZnS ceramics were partially melted at 980°C because ZnS nanopowders were directly used for the synthesis of ZnS ceramics.…”

Hydrothermally synthesized ZnS nanopowders comprising small and large particles were used to synthesize ZnS ceramics. Small particles (200 nm) existed in the gaps between the large particles (0.7 μm) and assisted the densification of the ZnS ceramics. ZnS ceramics sintered at low temperatures (<1000°C) exhibited small grains with large grain-boundary areas that provided diffusion paths for carbon ions from the graphite mold, resulting in carbonate absorption bands. ZnS ceramics sintered at high temperatures (≥1000°C) for a long time (≥2.0 hours) exhibited a dense microstructure with very large grains (>500 μm). The ZnS liquid phase, which was formed at approximately 980°C, assisted the densification and grain growth of the ZnS ceramics. A 3.0-mm-thick ZnS ceramic sintered at 1000°C for 16 hours showed a high Knoop hardness (321 kgf/mm 2 ) and a high transmittance of 71% in the wavelength range 6.0-12 μm without carbonate absorption bands.
