Scholarcy highlights

  • In this work, C-dots were synthesised inexpensively, using hydrothermal, one-step pathway from persimmon peel biowaste
  • The prepared C-dots were investigated by UV–Vis spectroscopy, photoluminescence spectroscopy, XRD, TEM, CHN, FE-SEM and FT-IR
  • Analyses resulted in different functional groups on the surface and led us to treat the solvatochromic method as convincing argument to resolve the dilemma of whether or not which functional groups are responsible for the intriguing observed optical properties
  • The increasing trend of emission efficiencies of homologues alcohols was interpreted in terms of exoergic interaction parameters included in Kamlet-Taft’s equation along with the endoergic solubility parameters and correspondingly the stiffness of solvent
