Near-infrared emissive carbon dots with 33.96% emission in aqueous solution for cellular sensing and light-emitting diodes

Self‐Quenching‐Resistant Red Emissive Carbon Dots with High Stability for Warm White Light‐Emitting Diodes with a High Color Rendering Index

“…Some studies been proposed that the excitation‐wavelength‐independent behavior is associated with a single type of chromophoric structure related to the surface molecular groups. [ 44 ] Thus, the corresponding luminescent mechanism may be ascribed to the surface molecular state fluorescence. [ 45,46 ]…”

Carbon quantum dots enhanced the activity for the hydrogen evolution reaction in ruthenium-based electrocatalysts

“…Carbon quantum dots (CQDs) are emerging nanomaterials that show great promise for bioimaging, 35 optical sensing, 36 catalysis 37 and photovoltaic applications. [38][39][40][41] CQDs with high stability, easy surface functionalisation, and high electrical conductivity are attractive materials for the design and fabrication of photo-electro-catalyst. [42][43][44] The variety of functional groups (-COOH, -NH 2 , -OH, -CQO etc.)…”

High production-yield solid-state carbon dots with tunable photoluminescence for white/multi-color light-emitting diodes

“…Compared with traditional phosphors using rare-earth elements [35] or heavy metals [36], the stable optical properties, low cost, and low toxicity of CDs makes them attractive as WLEDs phosphors. At present, WLEDs are produced using multiple phosphors of different colors or yellow phosphors combined with blue or UV chips [37][38][39]. The former involves complex production processes, whereas the latter leads to a low CRI and high CCT.…”
