Brief About Innovation

Production of carbon quantum dots (CQDTs)

High impact materials like carbon dots (CDTs), are newly rising carbon nanomaterials (CNMs) amongst the nanocarbon member and progressively it is turning into a rising star. Carbon dots are in general consisting of carbon nanoparticle of less than 10 nm in size termed as carbon quantum dots (CQDTs) and graphene nanosheets with a plane size much less than 100nm termed as graphene quantum dots (GQDTs). CQDTs have a broad range of application in extraordinary fields such as biosensing, bioimaging, drug delivery, photocatalysis, photovoltaic devices, and optoelectronics. Compared to traditional semiconductor quantum dots, the unique characteristics of the CQDTs are low toxicity, biocompatibility, low cost, chemical inertness, and similar fluorescence properties. We have a lab-scale process for the preparation of carbon dots which uses novel ultrasonic-assisted wet-chemical method with environmental control. The method also overcomes the above-mentioned drawbacks such as it is less time consuming, minimum amount of water and ammonia solution is needed for the neutralization step and additional experimental steps are not required to enhance the yield of the product.
