Abstract

Ascorbic acid-capped CdSe nanoparticles have been successfully synthesised at room temperature via a simple, one-pot environmentally benign solution growth technique without the use of additional stabilisers. The UV-vis absorption and photoluminescence spectroscopy (PL) showed that the particles exhibited quantum confinement in their optical spectra with emission in the blue region. The transmission electron microscopy (TEM) image showed that the particles are small and spherical in shape. The high resolution transmission electron microscopy (HRTEM) image confirmed the crystalline nature of the material while the Fourier transform infra-red (FTIR) analysis confirmed the capping of the nanoparticles by the ascorbic acid.
