Synthesis and characterization of poly(acrylic acid) stabilized cadmium sulfide quantum dots.
TL;DR: It is demonstrated that there is a critical COOH/Cd ratio that maximizes the photoluminescence intensity and quantum yield (QY) and above this critical ratio, which corresponds to smaller crystal sizes (3.7-4.1 nm) for each reaction set, the quantum yield decreases and the crystal size increases.

Does water chemistry affect the dietary uptake and toxicity of silver nanoparticles by the freshwater snail Lymnaea stagnalis
Ana López Serrano Oliver,Marie Noële Croteau,Tasha L. Stoiber,Mila Tejamaya,Isabella Römer,Jamie R. Lead,Samuel N. Luoma +6 more
TL;DR: The results suggest that correcting regulations for water quality could be irrelevant and ineffective where dietary exposure is important, and bioaccumulation and toxicity of Ag from PVP-AgNPs ingested with food are not affected by water hardness and by humic acids, although both could affect interactions with the biological membrane and trigger nanoparticle transformations.

A study of size dependent structure, morphology and luminescence behavior of CdS films on Si substrate
TL;DR: In this paper, the size tunable cadmium sulfide (CdS) films deposited by a dip coating technique on silicon (100) and indium tin oxide/glass substrates have been characterized using X-ray diffraction, Xray reflectivity, transmission electron microscopy, atomic force microscopy and photoluminescence spectroscopy.

Meso-2,3-dimercaptosuccinic acid: from heavy metal chelation to CdS quantum dots
TL;DR: In this paper, the authors used DMSA to act both as a sulfur source and a capping agent in the aqueous synthesis of CdS quantum dots under mild conditions, and the combination of 70 °C and pH 7.5 was determined as the best reaction conditions for a well-controlled reaction.

Gain and the threshold of three-dimensional quantum-box lasers
TL;DR: In this article, the electronic dipole moment and its polarization dependence are analyzed, and it is shown that the gain becomes maximum when the electric field of light is parallel to the longest side of the quantum box.
