Carbon Dots Derived from <i>Curcumae Radix</i> and Their Heartprotective Effect.

In the excitation wavelength range of 20 nm, as the excitation wavelength increased from 330 nm to 450 nm, the maximum emission wavelength of CRC-CDs was red-shifted and the fluorescence intensity ( Figure 1H ) showed a trend of increasing and then decreasing, indicating that CRC-CDs have excitation-related emission properties.
