Synthesis of Alloyed Cd _x Zn_{1- x} S Quantum Dots for Photovoltaic Applications

Cadmium-Based Quantum Dots Alloyed Structures: Synthesis, Properties, and Applications

“…The substrate after that was washed using ethanol, followed by repeating the process with the second and third precursors, dehydrated zinc acetate and sodium sulfide, respectively. Finally, a solution of methanol mixed with water was used for washing [46]. In this way, the chemical reaction occurs between the first deposited materials (cationic sources) and the next (anionic sources), so they can combine to introduce the required compound (Figure 3).…”

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

“…[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. [20] Reduced graphene-CdZnS nanocomposites have also been reported to have high photocurrent generation under sunlight illumination, with a direct relationship to the intensity of the exposed sunlight.…”

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

“…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 ]. To examine the solar-to-hydrogen energy conversion efficiency and photocatalytic activity, porous Cd 1−x Zn x S nanosheets with twinned phase junctions were manufactured using a cation-exchange method employing inorganic–organic hybrid ZnS diethylenetriamine nanoflakes with cadmium ions [ 22 ].…”
