Abstract As a type of room temperature phosphorescence (RTP) material, carbon dots (CDs) always show short lifetime and low efficiency. To counter these disadvantages, several strategies, such as embedding in rigid matrix, introducing heteroatom, crosslink‐enhanced emission, etc., are well developed. Consequently, lots CDs‐based RTP materials obtained. Doping CDs into various matrix is the dominant method for preparation long‐lived so far. The desired CDs@matrix composites display outstanding performances. Meanwhile, matrix‐free carbonized polymer dots‐based also widely Amounts possessing ultra‐long lived, multiple colored, dynamic emission successfully Herein, recent progress achieved corresponding efficient strategies mechanisms summarized reviewed detail. Due to possess excellent chemical stability, photostability biological toxicity, they exhibit great application potential fields anti‐counterfeiting, data encryption, monitoring. introduced this review. promising functional development long wavelength emitting with still challengeable, especially red near‐infrared materials.

Abstract Carbon dots (CDs)—carbon nanoparticles smaller than 10 nm—have attracted widespread attention owing to their excellent optical properties. However, high‐performing CDs often suffer from severe aggregation‐induced quenching in the solid state, which limits commercial applicability. Therefore, CD materials with efficient solid‐state luminescence are sought. As research on structure and photoluminescence mechanisms of has intensified recent years, strategies construct fluorescent tune emissions have broadened. This article reviews advances for attaining fluorescence CDs, describes specific ways properties this fluorescence, introduces latest applications resulting optoelectronics, biology, sensing, finally considers prospects future application current challenges facing development CDs.
