Abstract:
Fluorescent silica nanoparticles, which encapsulated dye DCF-BYT with thermally activated delayed fluorescence (TADF) were fabricated by a simple synthetic method. Even in the atmospheric aqueous environment, the obtained DCF-BYT nanoparticles exhibited extremely long TADF lifetime up to 9.33 ms, which imparts these nanoparticles with great potential in biological applications, like time-resolved fluorescence imaging.
