In this work, highly fluorescent N-doped carbon dot (CDs) were synthesized from food waste and the relationship between the chemical structure and the fluorescent properties were deeply investigated. The cat feed stocks driven from food waste was used for the model material. The chemical transition from model waste to CDs were studied. The core of the CDs was successfully self N-doped without extra pre-/post-treatments and resulted in high quantum yield as 23%. To demonstrate the conversion of real food waste into CDs, the hamburger sandwich leftover was utilized for CD synthesis. The food leftover driven CD had similar chemical/optical properties to that of the waste model, with quantum yield of 28%. The synthesized CD was applied to fluorescence probe for Fe3+ detection. It showed high selectivity, even under the interference of other metal. Moreover, the CD exhibited good cell viability over 80% and adjusted to bio-imaging material. |
