Size Control of Ultrasmall CdS Particles in Aqueous Solution by Using Various Thiols

Effect of different aqueous synthesis parameters on the size of CdSe nanocrystals

“…For 5/1 ratio, particles exhibited significantly blue shifted absorbance below 300 nm from 716 nm of the bulk CdSe band gap. Nosaka et al [32] proposed that this absorbance wavelength indicates the formation of relatively stable clusters which may become a crystalline structure for constructing CdSe NP.…”

“…The different functional group of the capping agent can be the reason for this size variation. In addition to the different pK sh (pK a for the SH group of the thiol group) of the thiol groups, which affect the concentration of thiolate-Cd complex, the non-ionic characteristic of the OH group in ME molecules might accelerate the stabilization of the complex, thus allowing to achieve smaller particles [32].…”

Photophysics and Photocatalytic Properties of Cd(OH)2-Coated Q-CdS Clusters in the Presence of Guanine and Related Compounds

“…Thiol-modified CdS produces selectivity in the reduction of CO 2 to yield higher amounts of formate to carbon monoxide (13). Aliphatic amines (6), thio compounds (8,14), aniline (15), and tryptophan (17) are known to affect the pho- 1 To whom correspondence should be addressed.…”

Electronic Properties of Q-CdS Clusters Stabilized by Adenine

“…(17)(18)(19)(20)(21)(22)(23)(24). A variety of thio compounds (25)(26)(27)(28) and biological molecules (19,20,(29)(30)(31) have been tried as capping agents to produce nanoparticles of CdS with narrow size distribution and to obtain a bottlable solid material. The use of polynucleotides as surface-capping agents demonstrated an influence of nucleic base composition of the polynucleotides on the stabilization of CdS nanoclusters (19,20).…”
