Abstract

Specific features of using luminescent sensors with transducers based on a sensitive layer containing quantum dots immobilized in polymer matrixes of some fluorinated copolymers are described. Features of the formation of an analytical signal in time are studied. It is found that, in the analysis of some iodinated organic compounds, damped fluctuations of the luminescence intensity of the sensitive layer around a steady-state value can occur. Modern ideas of nonlinear and wave diffusion in polymer layers are attracted to explain the observed effects. Study of the kinetics of sorption by an independent method confirmed the fluctuations of sorption near its equilibrium value. The results obtained were used for the development of luminescent sensors based on quantum dots.

基于Cdse / Cds / Zns量子点的发光传感器分析信号形成的特定特征

摘要

描述了将发光传感器与基于敏感层的换能器一起使用的特定特征，该敏感层包含固定在一些氟化共聚物的聚合物基质中的量子点。研究了及时形成分析信号的特征。已发现，在分析某些碘代有机化合物时，敏感层的发光强度在稳态值附近会出现衰减的波动。聚合物层中非线性和波扩散的现代思想吸引了人们对观察到的效应的解释。通过独立方法研究吸附动力学，证实了吸附波动接近其平衡值。获得的结果用于开发基于量子点的发光传感器。
