Abstract: 

This article presents the results of a study QD Langmuir monolayers on the water subphase and LB films transferred onto a solid surface. The monolayers of CdSe/CdS/ZnS QD stabilized by oleic acid without of supplements of amphiphilic matrix, was created. The monolayers was transfered on the solid substrate, what was proved by the AFM and the fluorescence spectroscopy methods. The fluorescence spectra of the LB films with variable numbers of layers was captured. Also the spectrum of fluorescence before and after the laser irradiation with the wavelength 473 nm and optical power 6 mW was captured. The decreasing of the fluorescence intensity after 12 minutes of impact by 30% was obtained.

Key words: 
Langmuir monolayers
Langmuir–Blodgett films
quantum dots
optical properties
