Scholarcy highlights

  • In this communication we report the preparation of fluorescent carbon dots from chitosan gel
  • We studied the photoluminescent properties of CDs prepared in different pH conditions
  • While CDs prepared at pH 3 give an intense sharp blue fluorescence, those prepared at pH 1 or 5 give a broad emission
  • It was observed that the emission was broad and less well defined, there was an enhancement of PL emission for the CDs prepared from chitosan/Ag or chitosan/Au nanocomposites
