It is shown that a hybrid nanocomposite structure can be created by integration of semiconducting materials with different dimensionalities: an array of quasi-1D GaAs whisker nanocrystals formed by molecular-beam epitaxy on a Si (111) substrate and 0

We have studied complexes between CdSe/ZnS quantum dots and metal-free porphyrin molecule in aqueous solution and in human blood plasma. We have established that in aqueous solution, transition of the porphyrin to a stable form occurs 2-5 h after for

The revealed absorption saturation and Fresnel diffraction of ultrashort laser pulses under resonant excitation of the basic exciton transition in CdSe/ZnS quantum dots (a strongly absorbing colloidal solution) have been explained by the processes of

A dissociative luminescent sensor for Ni2+, Co2+, and H+ ions in water solutions has been developed. This sensor is a complex made up of luminescent semiconductor hydrophobic CdSe/ZnS quantum dots (QDs) with azo-dye l-(2-pyridylazo)-2-naphthol (PAN).

The fluorescence of CdSe/ZnS nanorods in liquid-crystal and anisotropic polymer composites is studied. A high degree of the fluorescence anisotropy is shown. It is found that a solubilizer strongly affects the CdSe/ZnS orientation, which opens new po

We have developed a method for solubilization of hydrophobic CdSe/ZnS nanocrystals of the core/shell type, obtained by high-temperature synthesis in coordinating organic solvents. The method is based on chemical modification of the surface of the nan

A study was made of the induced absorption in amorphous selenium particles (average radius ~20 nm) embedded in a polymer. A picosecond pump and probe technique was used. The change in the absorption was measured in the spectral range 550–750 nm whe
