Multilayer structures based on matrices of CdSe and CdSe/ZnS nanoparticles in polyimide (PI) and poly[2-methoxy- 5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) were prepared and investigated. A comparison of photoluminescence of the various matrices excited by visible and ultraviolet laser...

Laser-induced luminescence of multilayer structures based on the solids of CdSe and CdSe/ZnS nanocrystals, different organic semiconductors and on the layers of organic semiconductors with embedded nanocrystals has been investigated. Drastic decrease of luminescence quantum yield is observed in...

Solid thin films of CdSe and CdSe/ZnS nanoparticles on different templates have been investigated under influence of power visible laser radiation. Composite structures including organic semiconductors and CdSe and CdSe/ZnS nanoparticles films have been fabricated. Luminescent and electron...

The films with low and high concentrations of CdSe/ZnS nanoparticles have been investigated under action of visible and ultra-violet laser radiation in a wide range of power densities and temperatures. Strong shifts of absorption and luminescence spectra without increase in their width have been...

CdSe/ZnS quantum dots in solution ad in condensed phase have been investigated by methods of laser induced luminescence. Anti-stokes photoluminescence (APL) of CdSe/ZnS nanoparticles in the solutions and in the films has been studied under action of laser radiation of various wavelengths. The...

Optical properties of the films with high concentration of semiconductor core-shell CdSe/ZnS nanocrystals under action of visible laser radiation in a wide range of power densities have been investigated. It's shown that in the films with ultimate concentration ofthe nanocrystals a...
