Synthesis SnO2:Bi2O3 Nanostructure Device for Bio Sensor

Abstract

Abstract SnO2:Bi2O3 colloidal NPs were synthesized by pulsed laser ablation of Sn:Bi target (50%:50%) in double distilled water (DDW) at room temperature. High purity Sn:Bi target (purity of 99.99%) was fixed at bottom of open a plastic cell containing of 2 ml DDW and DDW+ PVP which represent the liquid media. Ablation is carried out with laser operating at 1.064 nm wavelengths at flounce set in the range of 40.5J/cm2 and (60 laser pulses). The diffraction peaks in the XRD pattern broadened due to the particles in the sample are too small. The primary particle size calculated by Sherrer formula is about 150 nm. The spherical nanoparticles morphologies were carried out by scan electron microscope (SEM) analysis, exhibits spherical with average size distribution found to be 20 nm.
