“…In view of the reasons from literature survey, structural and optical properties of Badoped CdO films prepared by SILAR method [9], high T c ferroelectricity in Ba-doped ZnO nanoparticles [10], blue light emission from barium doped zinc sulfide nanoparticles [11] and, effect of particle size on multiferroism of barium-doped bismuth ferrite nanoparticles [12], it reveals that there is no report on the effect of Ba doping to the properties of CdO NPs. Therefore, we are reporting new results on the effects of Ba doping on the optical, structural and morphological properties of CdO NPs via TG-DTA, SEM, XRD, FT-IR, and UV-Vis-DRS techniques, respectively.…”

“…To prepare ZnS-based high-efficiency luminescent phosphors, transition metal and rare earth metal ions have been widely used as dopants [ 27 - 32 ]. However, studies on the effect of alkaline metal ions doping on the properties of ZnS are sparingly available except few reports on cubic structured ZnS nanostructures [ 33 - 35 ]. In this work, we report on the lower temperature synthesis of stable Mg-doped ZnS wurtzite nanostructures using hydrothermal technique and their luminescence properties.…”

Mg-doped ZnS hierarchical spheres have been synthesized via hydrothermal method using mixed solvents of ethylenediamine and DI water without any surface-active agent. The surface morphology and microstructure studies revealed that the hierarchical spheres were consisted of many well-aligned nanosheets with width 10 nm and length about 50 ~ 100 nm. X-Ray diffraction results show that the ZnS:Mg hierarchical spheres have wurtzite structure with high crystallinity. The absorption edge in the diffuse reflection spectra shifts towards lower wavelength with increasing Mg concentration, indicating an expansion in the bandgap energy that is estimated to be in the range of 3.28 to 3.47 eV. Blue-green photoluminescence with tunable intensity and peak position was observed depending on the Mg content. The Mg2+-activated ZnS phosphor can be good candidates for blue-green components in near-UV white light-emitting diodes.

“…From a pool of 100 publications on metal sulfide NPs, details of metal and sulfur sources used for the synthesis of these particles are obtained [5, 7, 10, 19, 21, 22, 25–27, 30–120] . Care was taken to include only studies that synthesized 0D nanomaterials (NPs) and used only a single source of sulfur for synthesis, which was commercially available at the time of writing.…”

Fascination with and the need for evermore increasing efficiency, power, or strength have been the cornerstones for developing new materials and methods for their creation. Higher solar cell conversion efficiencies, increased battery storage power, and lightweight strong materials are some that have been at the forefront of attention for these efforts. Materials created for most applications start as simple chemical compounds. A study of how these chemicals have been used in the past can be used to create new materials and new methods of production. Herein, a class of materials that are valuable in a multitude of applications, metal sulfide nanoparticles, are examined, along with how they are being produced and how new methods can be established that will help to standardize and increase production capabilities. Precursor–solvent combinations that can be used to create metal sulfide nanoparticles in the gas phase are also explored.
