Long-Lived Dynamic Room Temperature Phosphorescence from Carbon Dots Based Materials

Kaiti Wang et al.

Summary: As a type of room temperature phosphorescence (RTP) material, carbon dots (CDs) have short lifetime and low phosphorescence efficiency. Various strategies have been developed to improve these disadvantages, including embedding in rigid matrix, introducing heteroatom, and crosslink-enhanced emission. Doping CDs into different matrices is the main method for preparing long-lived CDs-based RTP materials. However, matrix-free CDs and carbonized polymer dots-based RTP materials have also been widely explored. The recent progress, efficient strategies, and emission mechanisms of CDs-based RTP materials are summarized and reviewed in detail. These materials show great application potential in anti-counterfeiting, data encryption, and biological monitoring due to their excellent chemical stability, photostability, and low biological toxicity.

Jian Yao et al.

Summary: Organic room temperature phosphorescent (ORTP) materials provide a promising research direction for phosphorescent oxygen (O-2) sensors due to their high sensitivity and rapid response to O-2.
