New strategy for the synthesis and characterization of monodisperse Zn7.23Cd2.77S10 nanoparticles

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

“…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.…”

“…Such a low lattice mismatch promises the introduction of Zn 2+ into CdS to form Zn x Cd 1−x S alloyed SNCs. Recently, Zn x Cd 1−x S nanoparticles [14,15], nanoflake dendrites [16], nanorods [17] and nanorod-based spherical architectures [18] have been fabricated by hydro-/solvo-thermal route. Zn x Cd 1−x S nanorods with tunable optical properties and photocatalytic activities can be synthesized by a microwave method [19].…”

Microwave-assisted preparation and characterization of Zn1−xCdxS nanoparticles in presence of an ionic liquid and their photocatalytic activities

“…Moreover, the bond length for Cd-S equals 279 pm, which is 8.1% longer than that of Zn-S. The small discrepancy in bond length facilitates the formation of alloyed material [16]. No peaks attributable to possible impurities are observed.…”

“…Tel. : +98 0451 5512201; fax: +98 0451 5512200. powders by heating about 1000 • C. Recently, Jiang and co-workers have successfully synthesized the nanomaterials in presence of oleic acid at 200 • C for 17 h [16]. Generally, these methodologies employ harmful chemicals, high temperatures, complicate equipment or isolation of oxygen.…”
