Abstract

Hexadecylamine-capped Mn-doped wurtzite CdSe nanoparticles have been successfully synthesized via a novel, facile method at low temperature. Optical spectroscopy, X-ray diffraction (XRD), electron paramagnetic resonance (EPR) transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), selected area diffraction (SAD) and energy dispersive spectroscopy (EDS) measurements are presented to confirm successful doping of the wurtzite CdSe. The nanoparticles obtained show quantum confinement in their optical properties with band-edge luminescence. The reduction in the emission intensity of the doped CdSe compared to the pure CdSe indicates the presence of impurity (Mn²⁺ ions) in the pure CdSe nanoparticles. XRD analysis reveals that the nanoparticles are of wurtzite structure while the HRTEM image confirms the crystallinity of the doped material.
