Abstract Exploration in the way of understanding the optical behavior and structure of carbon nanodots has been increased due to their vast application. Their emission dependency on excitation wavelengths is the more prevalent and controversial subject. In this report we considered the optical structure of hydrothermally synthesized carbon nanodots using citric acid and 2. 3-diaminopy... https://www.sourcebmxers.shop/product-category/bmx-crank-spindles-etc/
