Composite film structures containing ZnS, CdS nanoparticles prepared by MOC pyrolysis at low temperatures

New composite structures containing ZnS, CdS nanoparticles were prepared with bright light-blue colour of luminescence. The structures were formed by spraying organic solution of zinc or cadmium ditiocarbamate onto substrates at temperatures within the range 40..120DGC. It was established that the f...

Description
Summary:New composite structures containing ZnS, CdS nanoparticles were prepared with bright light-blue colour of luminescence. The structures were formed by spraying organic solution of zinc or cadmium ditiocarbamate onto substrates at temperatures within the range 40..120DGC. It was established that the film emission maximum monotonously shifts into short-wave spectral region at the decreasing substrate temperature: from 590 nm (Ts = 120DGC) to 500 nm (Ts = 50DGC) for ZnS and froth 510 nm (Ts = 120DGC) to 450 nm (Ts = 40DGC) for CdS. This fact can be explained by the quantum size effect: X-ray analysis has shown that researched films contain crystalline particles of 1..5 nm size.
