Fluorescenсе Properties of Complexes of Coumarin Derivatives/CdTe Quantum Dots under Interaction with Ammonia Molecules in Microconcentrations
In this paper we present the results of studies regarding the creation and the properties of the hybrid sensor film structures of polyvinyl alcohol with complexes of coumarin dyes and quantum dots CdTe. It is shown that the synthesized structures reveal changes in fluorescence intensity of 8-13 % (d...

| description | In this paper we present the results of studies regarding the creation and the properties of the hybrid sensor film structures of polyvinyl alcohol with complexes of coumarin dyes and quantum dots CdTe. It is shown that the synthesized structures reveal changes in fluorescence intensity of 8-13 % (depending on dye) in the presence of ammonia molecules in the environment in ultralow concentration (10 ppm). It is found experimentally that such changes for coumarin-7 were most significant at a concentration of 5.210 – 3 M. We found that entering of the colloidal CdTe quantum dots in the film structure causes to amplification of the fluorescence intensity of coumarin-7 by 57 %. |
