Carbon Dots@Allophane Core–Shell Nanoparticles with Long-Lifetime Room-Temperature Phosphorescence for Anti-Counterfeiting Applications

Visible-light-excited room-temperature phosphorescent carbon dots: preparation strategies, mechanisms, and applications

“…15–19 Due to their excellent optical properties, CDs are considered appropriate candidates for constructing long lifetime RTP materials. 20–22 Usually, the RTP performance of CDs can be enhanced by doping heteroatoms and embedding CDs into a matrix ( e.g. , silica (SiO 2 ), boric acid (BA), inorganic salts, and zeolites).…”
