“…[9][10][11][12] It was found that solvent, temperature, and reactant have significant effect on crystal structure and particle size of II-VI semiconductor nanoparticles, including CdS nanorods, ZnSe nanorods, CdS nanowires. [16,[89][90][91][92][93][94][95][96][97][98][99][100][101] Furthermore, wurtzite ZnSe and CdSe nanorods can also be synthesized by using n-butylamine, i.e., a monodentate amine, as solvent ( Fig. 1).…”

This Feature Article provides a brief overview of the latest development and emerging new synthesis solution strategies for II–VI semiconducting nanomaterials and inorganic‐organic semiconductor hybrid materials. Research on the synthesis of II–VI semiconductor nanomaterials and inorganic–organic hybrid semiconducting materials via solution strategies has made great progress in the past few years. A variety of II–VI semiconductor and a new family of [MQ(L)0.5] (M = Mn, Zn, Cd; Q = S, Se, Te; L = diamine, deta) hybrid nanostructures can be generated using solution synthetic routes. Recent advances have demonstrated that the solution strategies in pure solvent and a mixed solvent can not only determine the crystal size, shape, composition, structure and assembly properties, but also the crystallization pathway, and act as a matrix for the formation of a variety of different II–VI semiconductor and hybrid nanocomposites with diverse morphologies. These II–VI semiconductor nanostructures and their hybrid nanocomposites display obvious quantum size effects, unique and tunable optical properties.

“…300°C have been the most extensively tried route. Subsequently, lot of variants of this procedure have been reported with a variation in the nature of precursors, medium and temperature (Bowen-Katari et al 1994;Trindade and O'Brien 1996;Trindade et al 1997;Xie et al 1999;Gautam et al 2001;Hu et al 2001). Among them, in a method developed by Peng and Peng (2001), gaseous and poisonous dimethyl cadmium in the earlier methods was replaced by more safer-to-handle CdO solid.…”

New route for preparation of luminescent mercaptoethanoate capped cadmium selenide quantum dots

We report a synthesis of cadmium selenide quantum dots (Q-CdSe) by refluxing a mixture of cadmium acetate, selenium powder, sodium sulfite and 2-mercaptoethanol in N,N′-dimethyl formamide (DMF)/water solution. X-ray and electron diffractions suggest the formation of hexagonal phase of size quantized CdSe. Based on TEM analysis, the formation of nanoparticles with an average diameter of 3⋅5 ± 0⋅5 nm is inferred. Their sols in DMF and dimethyl sulphoxide (DMSO) gave characteristic absorption peaks at 300 nm and 327 nm, which is attributed to the formation of high quality, size quantized CdSe particles. Extracted particles from the sol were readily redispersed in DMF and DMSO, which were diluted further with water without losing their optical and colloidal properties. FTIR spectroscopy suggested the formation of 2-mercaptoethanol thiolate on the particle surface, with free -OH groups available for linkage. Sols in DMSO and their solutions in water displayed an intense photoluminescence (PL).
