Figure 3

The absorption (ABS) and fluorescence (FLSC) spectra of the PEI/CA-CDots prepared by the modified hydrothermal processing (——) are compared with those of the EPACDots obtained from the deliberate functionalization synthesis (- - - -).39 Also for comparison is the absorption of the PEI-CDots (-.-.-.-)38 (the corresponding fluorescence spectrum already shown in Figure 2). Inset: Photos of a dilute aqueous solution of the PEI/CA-CDots under ambient room light (left) and under sunlight (right).
