Syed Khadar, Paramasivan RajasinghAbstractA simple and novel one-pot synthesis of CdS, quantum dots from naturally available fruit sap Opuntia ficus-indica was performed. We have investigated a green route for the synthesis of CdS QDs using eco-friendly and naturally renewable Opuntia ficus-indica fruit sap as green template. Synthesized CdS QDs were determined by Fourier transform infrared spectroscopy, UV–visible (323 nm), X-ray diffraction (cubic structure), X-ray fluorescence, Dynamic light scattering (d50 = 9.56 nm), High resolution transmission electron microscopy (Spherical shaped). Overall the present work describes the green synthesis of CdS nanoparticles from Opuntia ficus-indica fruit sap with extrinsic crystallite size control in the quantum confinement range.
