Abstract:

The structure of a luminous field in a fluorescence layer containing CdSe/CdS/ZnS-based quantum dots and acting as a transducer in an optical fluorescent sensor is described on the basis of three-flux approximation. Differential equation system of three-flux approximation is solved by numerical technique. It is found that diffuse reflectance of the layer extremely depends on concentration of quantum dots in the layer and its physical thickness. Optimal parameters of the layer required for forming of maximum analytical layer are determined.
