Carbon quantum dots (CQDs) are a new type of carbon nanomaterial’s that are novel fluorescent. They are also one of the most important carbon nanomaterial’s. In the last few decades, more has been learned about how to make them, how to change them, and where they can be used. If a chemical reaction happens or not, the method of making CQDs from food waste can be divided into physical synthesis and chemical synthesis. Food waste that has enough carbon sources can also be used to make CQDs, but this hasn't gotten much attention. So, it makes sense for CQDs technology to use food waste as a starting point. Due to their good fluorescence performance, CQDs made from food waste can be used for analysis and sensing. Food waste is everywhere in the natural and living environment, and there is a lot of it. Even though a lot of work has been put into making multifunctional CQDs from biomass waste, there are still many problems to solve. First of all, scientists don't fully understand how CQDs give off light. For CQDs made from renewable biomass waste to be used in more places, its photoluminescence mechanism needs to be explained in detail and be widely known.
