Abstract: Synthesis and characterisation of Zinc Oxide nanoparticles by means of green approach using the bio component of Kalanchoe Tubiflora leaves is discussed in this research paper. The sample was characterized by X-Ray Diffraction (XRD) and UV-Vis spectroscopy. XRD confirms the growth of hexagonal ZnO wurtzite structure. The size of nano crystallites calculated using Debye-Scherrer’s formula as 31.6nm. Energy band gap of 3.26eV and absorption at 347nm shows the presence of Zinc Oxide nano structure.

Keywords: Green synthesis, nanostructure, organic solar cells, energy conversion

I. INTRODUCTION

The concept of nanotechnology by Richard Feynman manages and manipulates functional systems at the molecular or supramolecular scale. Nanotechnology plays a vital role in the field of advanced computing, medicines, electronics, photonics, textile engineering etc. because the nanoparticles exhibit superior properties than bulk materials [1].
Metal oxide nanoparticles have many impressive properties and thereby have broad range of applications like cosmetology, sensors, including transdermal antibiotic patches etc. Having wide bandgap, large binding energy and high piezoelectric properties Zinc Oxide nanoparticles (ZnO NPs) can be employed in the field of nanomedicines, energy conversion, photo catalyst and photo oxidizing agent.
Nanoparticles can be synthesised from sol-gel method [2], inert gas condensation [3], laser ablation [4], solvothermal [5], hydrothermal [6] etc. Chemical method often involves high temperature, high pressure, inert gas atmosphere and use of toxic capping and stabilizing agents. Biological approach using plants and animals is an alternate to the chemical method for synthesising nanoparticles [7-10]. Nanoparticles exhibits higher surface area to volume ratio with diminution in the size, distribution and morphology.

Green synthesis of ZnO NPs obtained from Kalanchoe Tubiflora leaves extract which was collected from Coimbatore, Tamil Nadu, India. Studies show that Kalanchoe Tubiflora is a potential anti-cancer agent [11]. To best of our knowledge, the use of leaf extract of Kalanchoe Tubiflora for the green synthesis of ZnO NPs has not been revealed. Hence, the present work was carried out to synthesis and characterization of ZnO NPs using Kalanchoe Tubiflora
