Structure and Photoluminescence of Carbon Dots: Different Opinions

Abstract

Princy Garg

Carbon Dots (CDs), a novel type of carbon-based nanomaterial, have drawn board research interest for years, due to its inherent physical and chemical properties and favourable characteristics, such as high stability, different optical features, outstanding compatibility, low cost, and eco-friendly. In this review, we look on the classification of CDs which are based on their different mechanism and also describe their various synthesis processes as well as their optical properties, such as fluorescence and photoluminescence. There are numerous review articles with differing viewpoints on the synthesis of CDs, but there is no clear picture of CDs; the topic is an open for debate. In the last, there is a conclusion of different opinions given by different authors who provided the synthesis of CD and photoluminescent.
