Abstract
The present study reports preparation of copper and copper sulfide nanoparticles using leaf extract of Urtica dioica. The effect of heating on the nanoparticles has also been discussed. Nanoparticles have been characterized using X-ray diffraction, UV-visible absorption, scanning electron microscopy and energy dispersive X-ray. Improvement in crystallinity of the nanoparticles was observed on heating in the temperature range 180-500 °C. The crystallite size of the copper nanoparticles heated at around 500 °C was found to be about 28 nm whereas that of copper sulfide nanoparticles heated at around 250 °C was found to be approximately 6 nm.
