Mn-doped carbon dots as a visible-light-driven catalyst for degradation of acid fuchsin and malachite green

Emerging and Versatile Platforms of Metal‐Ion‐Doped Carbon Dots for Biosensing, Bioimaging, and Disease Therapy

“…in 2004, [23] great efforts have been made to regulate their structures and properties, aiming at improving the photoluminescent quantum yield, broadening the photoluminescence spectral coverage, and endowing CDs with special applications [24–29] . Metal ion‐doping is an effective approach to tune the physicochemical properties of nanomaterials due to the extensive free electrons, unoccupied orbitals, and large atomic radius of metal ions [30–34] . CDs have abundant electronic energy levels, and have been verified to be excellent electron donors or acceptors in many previous studies [35] .…”

“…[24][25][26][27][28][29] Metal iondoping is an effective approach to tune the physicochemical properties of nanomaterials due to the extensive free electrons, unoccupied orbitals, and large atomic radius of metal ions. [30][31][32][33][34] CDs have abundant electronic energy levels, and have been verified to be excellent electron donors or acceptors in many previous studies. [35] As expected, the doping of CDs with metal ions greatly changes the electronic distribution and the energy gap of CDs, and thus brings noticeable alterations in photophysical, magnetic, and electronic properties.…”
