  • The capacitance values were found to be increased with the effect of co-doping and the capacitance values lie in the range of 2.6 µF/cm2 to 0.5 µF/cm2
  • Carbon nanodots have currently emerged as a unique and promising material focusing on advanced applications especially in the field of optoelectronic and energy storage devices
  • The presence of major elements and the functional group identification was done with the aid of EDS and FT-IR spectral analysis, the morphology and size were analyzed by high-resolution TEM analysis and photophysical characteristics were investigated from the fluorescence measurements
  • The doped carbon dots were explored for their energy storage application and their super capacitance characteristics
  • The capacitance values of the carbon dots were found to be increased with the effect of co-doping with the first-row transition elements and the capacitance values were in the range of 2.6 µF/cm2 to 0.5 µF/cm2 and are in tune with the capacitance values for carbon-based materials including graphene and C-dots reported in the literature
  • The cyclic voltammetric loops were found to be sufficiently rectangular in shape, desirable for a supercapacitor, and the rectangular areas were found to be increased with increase in scan rate
