Zno: Sno2 Nano-Composite by Laser Ablation Method to Fight Diseases-Causing Bacterial and Fungi

Abstract

Nano-particles of zinc oxide (ZnO) and tin oxide (SnO2) have been produced by the process of pulsed laser ablation in water. the optical, structural, morphological, and of all samples (ZnO, SnO2, and ZnO: SnO2 composite) Nano-particles were examined by employing UV–Vis spectroscopy, X-ray diffraction (XRD), atomic force microscopy, and evaluation of anti-bacterial and antifungal properties respectively. The XRD patterns demonstrate that generated ZnO Nano-particles are nano-0crystalline and have a hexagonal wurtzite structure, whereas the structure of tin oxide is tetragonal rutile. It was discovered that the direct optical energy gap of each and every sample fell somewhere in the range of (4.8), (4.8), and (4.9) eV, respectively. Anti-bacterial and antifungal activities can be observed in the Nano-particles that were produced.
