Light-nutrition coupling effect of degradable fluorescent carbon dots on lettuce
The increasing application of carbon dots (CDs) inevitably leads to environmental leakage. To be environmentally friendly, degradable CDs will become a mainstream agricultural application in the future. We prepared three CDs with different functional groups.

description | The increasing application of carbon dots (CDs) inevitably leads to environmental leakage. To be environmentally friendly, degradable CDs will become a mainstream agricultural application in the future. We prepared three CDs with different functional groups. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis showed that -C&z.dbd;C-H and C&z.dbd;O groups on the CD surfaces are major sites for oxidative degradation of the CDs. The pyridine N is responsible for photoproduction of &z.rad;OH and &z.rad;O

Degradable fluorescent N-doped CDs are oxidized and degraded into substances that can be used for lettuce growth. Their excellent light conversion characteristics promote the utilization of the CD degradation products by lettuce. |
