Description

ZnO nanoparticles were successfully synthesized using the eco-friendly green method, where Zinc nitrate was reacted with the extract of Callistemon Viminalis’ (Bottle Brush). The structural and optical properties were determined using X-Ray diffraction and Photoluminescence (PL) spectroscopy. The XRD showed that zincite was synthesized having a hexagonal structure and a room temperature PL was used to determine the luminescence, strong emission peaks were observed at 377,6nm, 491,8nm and 533,6nm. These emissions show that ZnO is a suitable material to be used for luminescence.
