Summary: The structural, optical, and magnetic properties of ZnS and Fe-doped ZnS quantum dots were investigated. The results showed that the Fe doping led to a decrease in crystallite size, an increase in lattice constant, a blue shift in bandgap, and a shift in emission spectrum from ultraviolet to violet.

Summary: Superparamagnetic N-doped graphene oxide (GO)- with ZnS nanowires were synthesized by a one-step hydrothermal method with codoped Ga3+, In3+, Al3+ and Cr ions for enhanced water treatment and biomedical applications. The In0.02Cr0.02Zn0.96S nanocomposite showed superior photocatalytic efficiency due to the best combination of In and Cr as dopants. Characterization techniques such as XRD, FESEM with EDAX, VSM, UV-Vis, XPS, and fluorescence spectroscopy were used to analyze the synthesized nanocomposite materials and investigate the correlation between magnetic and photocatalytic properties. XPS revealed a higher percentage of defects in the Cr and In codoped composite, resulting in a photocatalytic efficiency of 94.21%.

Summary: The systematic investigation of aquatic Zn1-xNixS (0 <= x <= 0.04) nanocrystals was conducted, focusing on structural, spectroscopic, local atomic structure, and magnetic properties. The doping of Ni ion resulted in a shrinkage of the energy band gap and the emergence of defect-induced paramagnetism in the nanocrystals. Multiple analytical techniques, such as X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and photoluminescence spectroscopy, were employed to study the synthesized samples.

Summary: The use of sulfidogenic bioreactors is a biotechnology trend for recovering valuable metals from mine-impacted waters. In this study, ZnS nanoparticles were produced using green H2S gas generated by a sulfidogenic bioreactor. The nanoparticles exhibited a spherical-like shape and had a principal zinc-blende crystalline structure, semiconductor character, and fluorescence emission in the UV-visible range. In addition, the nanoparticles showed photocatalytic activity in degrading organic dyes and antibacterial properties against various bacterial strains.

Summary: ZnS quantum dots (QDs) were fabricated without a capping agent using the co-precipitation technique. The effects of different annealing temperatures (non-annealed, 240 degrees C and 340 degrees C for 2 h) on the structural and optical characteristics of ZnS QDs were investigated. The results showed that the annealing temperature influenced the dot size, energy band gap, and reflection spectra of the ZnS QDs.

Summary: In this study, photo-responsive ZnS nanostructures were synthesized using MPA and PVP as capping agents, showing enhanced photocatalytic activity towards crystal violet degradation under UV light. Structural analysis and FT-IR studies were used to determine the effects of capping agents and the formation of nanostructures. The unique optical properties, effective charge separation, and higher surface area of ZnSM1 contributed to its outstanding activity in degrading organic pollutants beyond the UV region.

Summary: The study focused on the structural, electronic, and magnetic properties of non-metal-doped ZnS monolayers using spin-polarized plane-wave DFT with Generalized Gradient Approximation. B- and C-doped ZnS monolayers exhibited half-metallic behavior, while N-doped ZnS monolayer showed semiconducting nature. The magnetic moments primarily originated from 2p orbitals of the dopant atoms, demonstrating d(0) ferromagnetism.
