摘要：

A dual-emission fluorescent nanocomposite was prepared. Carbonized polymer dots were prepared by a one-step hydrothermal method using chitosan as the carbon source. Silver nanoclusters were synthesized by UV lamp irradiation using polymethacrylic acid as the stabilizer. The carbonized polymer dots and silver nanoclusters were self-assembled by electrostatic force to prepare a dual-emission fluorescent nanocomposite that responds to temperature changes. The carbonized polymer dots-silver nanoclusters (CPDs-AgNCs) nanocomposites showed two emission peaks at 401 and 609 nm under the same excitation wavelength. It has an excellent linear relationship between 20 degrees C and 80 degrees C. And by introducing the dual-emission fluorescent nanocomposite into the membrane system, the temperature was successfully detected, which Broadens the application of rapid and convenient temperature detection.
