Abstract
The temperature sensitivity of photoluminescence of synthesized composites based on differently charged biopolymers with colloidal CdSe/ZnS quantum dots and erythrosin B dye was studied. Due to the combined action of the mechanisms of temperature quenching and resonant energy transfer from quantum dots to the dye, the dynamic range of the analytical signal of the quantum dot photoluminescence intensity increases, which can be used to create dynamic temperature sensors.
