This study utilizes Pdots with fluorescencethen incorporate combine with thermochromic dyes. These hybrid nanomaterials exhibit significant changes both in absorptionemission. Specifically, at room temperature, deep red color but no fluorescence could be seen. At the temperature higher than 37oC, these materials become transparent accompanied by the appearance of strong emission.

This study utilizes different types of Pdots with RGB fluorescencethen incorporate combine with thermochromic dyes. Upon the temperature changes, these hybrid nanomaterials exhibit significant changes both in absorptionemission.In addition, we have successfully applied this material to printers.

This study successfully removed the environmental hormones of bisphenol A. In addition, the low biotoxicity of the semiconducting polymer nanoparticles used in this experiment was also confirmed by literature journals. And this hybrid nanoparticle has good repeatability when it used in other materials, indicating that it has potential to apply on food, medicinedaily necessities.
