Paper Abstract
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 properties of the structures have been
investigated. Luminescence quantum yield of these nanocomposite structures is shown to exceed that of the films of
organic dyes by two orders of magnitude for CdSe nanoparticles with ZnS shell. As for quantum dots without the shell
their luminescence quantum yield appears to fall drastically in the films and even in the matrices of organic
semiconductors compared to the solution. The presence of CdSe films in multi-layer structures of polyimides leads to
abrupt increase in their conductivity by several orders of magnitude. The prospects of development of photovoltaic
elements and light-emitting devices including the films with high concentration of CdSe and CdSe/ZnS quantum dots
are discussed.
