Further decrease of concentration will lead to the linear dilution and increase of concentration lead to twist of the molecules and increase of screening of counter charged units. In the case of CdTe quantum dots (unlike CdS), the luminescence spectrum of the film is shifted to longer wavelengths and decreasing its width at half-height that is a result of energy transfer processes, which efficiency is significantly increases in polymer matrix due to reduction of the distance between the particles. It has been established that in multilayer structures "polymer - quantum dots" with increasing wavelength of film radiation increases transport efficiency of the light flux through the glass substrate medium. It was determined that the temperature behavior of the quantum dots in polymeric matrix is significantly differs from the behavior in solution. First, the temperature sensitivity of particles in film is several orders lower than in solution. Secondly, the dependence of temperature coefficient of the particle on their size in film is not a back square, that clearly observed in the solution. This difference can be explained by the predominant influence of the energy transfer processes, which effectiveness in film is much higher.
