A comprehensive review on multifunctional smart carbon dots (C dots) based aerogel

Abstract

Till now from the time of invention of carbon dots (CDs), continuously grabbing the attention of the researchers due to their unique characteristics like nano size range (<20 nm), surface activity, photo luminescent behavior, non-toxicity, etc. Since, last decades CDs grab attention in the field of functional aerogel preparation. Functional CDs based aerogel is an emerging material which combines the characteristics of aerogel (high specific surface area, light weight, high porosity, etc.) as well as the CDs. Therefore, this review has been conducted to represent the current scenario of CDs based aerogel, their characteristics, and applications in various fields. The CDs based aerogel luminescent behavior at different wavelength, fluorescence quantum yield, and fluorescent quenching capability have found huge application in the field of sensing. Moreover, CDs based aerogel application in food sensing purpose is limited. Bio-based CDs aerogel with similar functional properties is an emerging area where further research is needed.
