Scholarcy highlights

  • The first use of the combination of ammonium citrate and ethylenediamine tetraacetic acid as coordinating precursors for the synthesis of highly fluorescent multicolour nitrogen-doped carbon dots is reported
  • A single component white-light CD point with high fluorescence efficiency was obtained by surface control
  • The white light may be attributed to the overlap of diverse light emission induced by electron transitions between the energy levels
  • To avoid aggregation-induced solid-state fluorescence quenching, multicolour carbon dots-based sandwich glasses with various colour emission was fabricated, which is anticipated to be compatible with the all-optical light-emitting diodes
