Effect of Temperature on the Photoluminescence of CdSe/ZnS Quantum Dots in a Biopolymer Composite with Erythrosin B
摘要
Abstract
The temperature sensitivity of photoluminescence (PL) of synthesized composites based on differently charged biopolymers with colloidal quantum dots CdSe/ZnS and erythrosin B dye was investigated. The dynamic range of the analytical signal of the intensity of quantum dot photoluminescence broadens under the combined action of temperature quenching and the resonance energy transfer from the quantum dots to the dye, which can be used to create dynamic temperature sensors.
