AgSnS (ATS) has been reported to have a band gap of 1.33 eV and is expected to be a suitable material for the light-absorbing layers of compound thin-film solar cells. However, studies on solar cells that use ATS are currently lacking. The objective of this study is to obtain high-quality ATS thin films for the realization of compound thin-film solar cells using vacuum deposition and sulfide annealing. First, glass/SnS/Ag stacked precursors are prepared by vacuum deposition. Subsequently, they are converted to the ATS phase via sulfide annealing, and various process conditions, namely, annealing time, annealing temperature, and number of steps, are studied. By setting the heat treatment temperature at 550 °C and the heat treatment time at 60 min, a high-quality ATS thin film could be obtained. Multi-step heat treatment also produces thin films with nearly no segregation or voids.

The production, conversion and storage of energy based on electrocatalysis, mainly assisted by oxygen evolution reaction (OER), plays a crucial role in alkaline water electrolyzers (AWEs) and fuel cells. Nevertheless, the insufficient availability of highly efficient catalyst materials at a reasonable cost that overcome the sluggish electrochemical kinetics of the OER is one of the significant obstacles. Herein, we report a fast and facile synthesis of vapor phase deposition of dual-phase nickel sulfide (Ni-sulfide) using low-temperature annealing in the presence of HS and demonstrated as an efficient catalyst for OER to address the issues with sluggish electrochemical kinetics.

Cadmium zirconium sulphide (CdZrS) nanoparticles (NPs) were prepared using a sol-gel method. The effect of different annealing temperatures on the structural, morphological, optical, and compositional properties of CdZrS NPs was investigated. The structural investigation revealed that the CdZrS samples exhibit hexagonal and cubic structures in both the as-prepared and annealed samples.

High-temperature carbonization typically used in the preparation of advanced electrocatalysts poses significant challenges in preserving abundant functional groups essential for reactant adsorption and component stabilization. To address this, a solvothermal synthesis followed by non-carbonization annealing approach is proposed to fabricate a series of cobalt-based organic-inorganic hybrids derived from cobalt-based glycerate nanospheres (GNs). Notably, annealing in phosphorous and inert atmospheres preserves the solid nanospherical structure, whereas treatment in sulfur-rich environments results in the formation of hollowed nanospheres.

Article Synopsis
- - The study explored how different heat treatments affected the thermoluminescence (TL) and structure of zinc sulfide (ZnS) samples, revealing that annealing increased the proportion of the hexagonal wurtzite phase.
- - The best thermoluminescence intensity was found in a sample with 8.2% wurtzite and 91.8% cubic zinc sulfide, with the analysis showing well-formed, aggregated ZnS nanoparticles.
- - The researchers used advanced techniques to analyze TL glow curves, identifying multiple trapping energy peaks and determining activation energies related to electron traps in the samples.

In the present study, a green, scalable, and environmentally friendly approach was developed for the fabrication of BiS-decorated CdS nanoparticles with an efficient hydrogen generation ability from the water. As a sulfur source, thiourea was used. The process was completed in two stages: mechanical activation and thermal annealing.
