Carbon dots (CDs) is a much explored new class of material developing now-a-days for a wide variety of applications due to their promising properties of fluorescence, simple synthetic approaches, good bio compatibility and various detection applications. The demand for green chemistry and cost-effectiveness leads to synthesize C-dots from natural sources. Nanometre sized carbon dots with unique optical properties of great importance due to its interesting wide applications. Natural Carbon Dots and Nitrogen doped carbon dots (N-CDs) were prepared from Natural sources by hydrothermal method. The CDs giving good water dispensability, strong blue fluorescence emission colour provide an excellent photo and pH stabilities. The fluorescence of CDs is resistant to the interference of bio molecules, metal ions and high ionic strength. Carbon dots with less than 100 nm sizes have been as a fascinating tool in sensing and bio imaging. Carbon dots can be naturally extracted from various parts of plants like flowers, leaves, seeds etc. This review presents the current progress in the development of CDs with an emphasis on Synthesis methods, fluorescent properties and applications in sensing, imaging and catalysis.
