The strucrture of CdS quantum dots 0,3% (mass), stabilized by the solution of the mercaptosuccinic acid in the gel matrix 50% THEOS is investigated by small-angle X-ray scattering (SAXS). Application of modern methods of SAXS data interpretation, including procedure of ab initio modeling of particle structure, allowed us for the to reveal structural organization of both individual nanoparticles and of their clusters incorporated in the polymer matrix. As a result, the shape, size, and size distribution of the obtained nanoparticles and their clusters depended on the structure of the gel matrix used as a formation medium.

Magnetic Iron Oxide Quantum Dots (MIOQDs) were synthesized using Moringa oleifera leaves through green technique i.e., Microwave treatment. The synthetic method is highly rapid, simple and economical. MIOQDs were formed by reduction of ferric chloride (FeCl3) solution with Moringa oleifera leaf extract without any influence of alkaline conditions which opens a new arena for the phytosynthesis of nanoparticles. MIOQDs structural characteristics were scrutinized by Powder X-ray diffraction method, FESEM, TEM, UV –Visible Spectroscopy, Photoluminescence Emission Spectroscopy. The ultraviolet-visible spectrum recorded for the aqueous media iron nanoparticles showed an absorption peak at around 330 nm. Powder X-ray diffraction showed that the particles are crystalline in nature, with both hematite and maghemite structure.
