Physical Properties and Light Energy Harvesting Efficiency of Silica Nanoparticles

Abstract

In this research, SiNPs and f-SiNPs with biocompatible molecules are used for solvents of nanoparticles employing dye methyl orange, in which the absorption efficiency of photo energy is quantities analyzed in the presence of sunlight. The properties of photo-energy harvesting of nanoparticles solvents have assessed in the form of some important physical parameters such as density, friccohesity, surface tension and viscosity. The density tendency of all type samples of nanoparticles were increased with light energy harvesting efficiency. The samples of SiNPs have highly viscous properties expressed exposed sunlight and the lowest of methyl orange dye. The mostly samples of nanoparticles have randomly expressed less viscosity, surface tension and friccohesity after sunlight exposed and few have increased. The analytical results were obtained in this study of the events of photo energy harvesting phenomena from plotted of Tauc graphs for energy gap depended on certainly of nanoparticles, in which found that after sunlight exposed nanoparticles shown energy level move toward at conduction energy gap.
