Influence of stabilizers on the structure and properties of Cd _x Zn _{1– x} S nanoparticles by sonochemical method

Critical analysis of biophysicochemical parameters for qualitative improvement of phytogenic nanoparticles

“…Sometimes, the initial concentration of metal ions selected for their nanoscale synthesis and their ionic diameter remain high enough to cause the synthesis of large sized NPs. 15 Increasing the concentration of metal salts up to a level has been shown to be positively correlated with the yield of green synthesized NPs (Table 6). The possible explanation for that-when initial salt concentration is very low, the relative number of metal ions remains also very low compared to the number of biomolecules available for reduction of metal ions in a given volume, that is, there is still enough reducing agents left for the reduction of metal ions.…”

“…The size control of nanomaterials is of utmost importance for their biomedical implications. Gahramanli et al 15 reported that the sizes of nanocomposites (CdxZn1-xS) may effectively vary with the types of capping agents used during their synthesis and this size controlling effects of capping agents might be ascribed to the changing energy status of capping agents and NPs and also to their molecular interactions (interaction chemistry) with NPs leading to the free energy change of latter. Sometimes, the initial concentration of metal ions selected for their nanoscale synthesis and their ionic diameter remain high enough to cause the synthesis of large sized NPs.…”

“…[5][6][7] The present physical and chemical methods (including both top-down and bottom-up approaches) for nanoparticles (NP) synthesis still have to depend on the use of a lot of toxic and environmentally hazardous reagents, which might impose severe detrimental effects on the environment, ecosystem and public health; and are labor intensive, energetically inefficient and expensive. [8][9][10][11][12][13][14][15] These hurdles compelled researchers to think another way and to make use of biomolecules for NPs synthesis aiming to develop facile, inexpensive, energetically efficient and eco-friendly technologies (green technology) for biocompatible NPs synthesis (Figure 1).…”

Theoretical Insights into Pressure‐Driven Stability and Optoelectronic Response of Cd0.75Zn0.25S Alloy for Blue–Violet Display

“…The advanced technology has directed us to further investigate the technological advancements in the growth of ternary alloys along with their efficient applications to overcome a range of hydrothermal, spray pyrolysis, microemulsion, vapor transport chemical conversion, and reverse micelle synthesis techniques. [8][9][10][11][12][13][14][15] The quantum-dot structures of CdZnS are also reported to be fabricated by the SILAR method, the coprecipitation method, and the noninjection one-pot synthesis technique. [16][17][18][19] Moreover, the photocatalytic and energyconversion activities of porous CdZnS twin-phase junction thin films have been investigated by fabricating them through cation-exchange techniques.…”

Pressure-Induced Bandgap Engineering and Tuning Optical Responses of Cd0.25Zn0.75S Alloy for Optoelectronic and Photovoltaic Applications

“…The CdZnS ternary alloys are one of the wide bandgap semiconductors that have high stability and are used in the fabrication of photovoltaic, photoconductive, photoluminescent, photocatalytic, and luminescent devices [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Thin films of CdZnS alloys have been synthesized using limited solid solutions of cadmium–zinc sulfides [ 8 ], as well as a chemical bath deposition technique [ 9 ], whereas nanocrystals and nanocomposites have been reported using the successive ionic layer adsorption and reaction (SILAR) method [ 10 ], the sonochemical method [ 11 ], the hydrothermal method [ 12 ], the solvothermal method [ 13 ], the microemulsion technique [ 14 ], vapor transport chemical conversion [ 15 ], spray pyrolysis [ 16 ], and reverse pyrolysis [ 17 ]. Quantum dots of CdZnS alloys have also been prepared using sequential ionic layer adsorption and reaction techniques [ 18 ], the non-injection one-pot approach [ 19 , 20 ], and the co-precipitation method [ 21 ].…”
