CQDs Technology

Carbon Quantum Dots (CQDs) show high energy by transition of electrons at n-π and π-π in applications where energy harvesting is required and observed that high atomic number significantly changes the properties of QDs. Biofunctionalizations allow improvement in different physiochemical properties of QDs. We explore various synthesis procedures and surface passivation of QDs to make them application-based tuneable nanomaterials. CQDs provide an efficient and cost-effective light source alternative with proper spectral composition to intensify the photosynthetic rate of plants. Utilization of CQDs in agricultural applications are dependent of their properties and surface chemistry.

Only part of the sunlight can be absorbed and utilized by plants, and the current utilization rate of light energy by plants is only about 5%. Photosynthesis involves the absorption of light energy, electron transfer, photophosphorylation, and carbon assimilation, mainly occurring in the chloroplast. Chlorophyll is the main photosynthetic pigment and acts as a light‐harvesting antenna. Chlorophyll is excited by light, converts light energy into electrical energy, promotes electron transfer in the photosystem, and generates ATP, which is converted into active chemical energy for CO2 fixation to generate biomass. CQDs make full use of the solar radiation irradiating the earth's surface for photosynthesis is the key to improving agricultural yield. Therefore, CQDs technology is to maximize the use of solar energy, artificial photosynthetic systems are explored with our products.

The slow-releasing nano-fertilizer improves plant physiological properties and various grains and lettuce nutritional parameters, and its application is therefore especially beneficial for progressive nanomaterial-based agriculture productivity. We have developed key elements passivation with CQDs for nano-delivery and sustained delivery of minerals for maximum utilization.
