Mechanochemical solid state synthesis of (Cd0.8Zn0.2)S quantum dots: Microstructure and optical characterizations

“…Rafea et al [37] prepared the stoichiometric cubic Cd 0.5 Zn 0.5 S phase by dip coating method onto glass substrate. Raviprakash et al [38] and Li et al [39] obtained the hexagonal (wurtzite) CdZnS phase by chemical spray pyrolysis and chemical reaction, respectively. In most of the above cases, the hexagonal phase was found to be present as a single phase.…”

“…Structural and micro/nano structure features are also revealed from high resolution transmission electron microscopy (HRTEM) images, which agree quite well with X-ray measurements. The main objectives of this work are to (i) synthesis CdZnS QDs from its elementary constituents in a single step, (ii) investigate the synthesis mechanism of CdZnS QDs by MA, (iii) quantitative estimations of both cubic and hexagonal CdZnS QDs prepared by MA and (iv) quantification of lattice imperfections present both in cubic and hexagonal CdZnS QDs to interpret changes in properties of CdZnS QDs with a proper justification which are not investigated in earlier works on CdZnS QDs [32][33][34][35][36][37][38][39].…”

One-pot synthesis of ZnxCd1−xS nanocrystals with tunable optical properties from molecular precursors

“…However, the tuning of physical and chemical properties by changing their particle size could also cause some problems (such as the instability of very small nanoparticles), which may greatly limit their applications. To address this problem, a new strategy to tune their optical properties has been developed by changing their constituent stoichiometries in mixed ternary II-II -VI SNCs [14][15][16][17][18][19][20][21]. For these homogeneous II-II -VI SNCs, both the confinement potential and the interfacial strain change with the composition, and therefore the energy band-gap can also be tuned with the composition even at a constant size.…”

“…Zn x Cd 1−x S nanorods with tunable optical properties and photocatalytic activities can be synthesized by a microwave method [19]. Zn x Cd 1−x S nanostructured films with controllable optical properties have been prepared by dip-coating [20] and spray pyrolysis technique [21]. One of the most predominantly employed methods for preparing SNCs involves the pyrolytic degradation of organometallic precursors in a coordinating phosphine or amine solvent [22].…”

The electronic states calculated using the sinusoidal potential for Cd1−xZnxS quantum dot superlattices

“…Until now, the study of Cd 1−x Zn x S thin films remains one of the primary interests in fundamental and applied researches as well [1][2][3][4][5][6][7][8][9][10][11][12]. In fact, Cd 1−x Zn x S is the most appropriate to be used as window layer material in solar cells based on conventional p-type absorber layer like CuInSe 2 [13,14] or on quaternary compounds such as CuIn x Ga 1−x Se 2 or CuSnS z Se 1−z [15].…”
