Abstract
We herein report the synthesis of high quality hexadecylamine (HDA)-capped CdSe nanostructures via a facile and effective non-organometallic method. By varying the growth temperature we monitored the size, optical properties and morphology of the as-synthesised CdSe nanoparticles. The nanoparticles were characterised using UV–vis absorption and photoluminescence (PL) spectroscopy, Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), transmission electron spectroscopy (TEM), high resolution electron transmission microscopy (HRTEM) and energy dispersive spectroscopy (EDS). The nanoparticles obtained were of high quality and monodispersed with high absorption and emission features. The emission and absorption maxima of the as-synthesised materials were red-shifted as the growth temperature increased indicating increase in particle size. The XRD analysis showed phase transition from cubic to hexagonal while the TEM images consist of both spherical and elongated particles as the temperature increased from 110°C to 200°C. The FTIR spectra confirmed the capping of the as-synthesised material by HDA while the EDS confirmed the presence of the corresponding elements.
