Low Conductivity of Green Synthesis Selenium Nanoparticles
Unique properties of Selenium (Se) and its allied nanoparticles are of great interest in the fields of chemistry and engineering. However, widespread applications of nanoparticles, especially Selenium nanoparticles (Se NPs) call for synthesis routes involving eco-friendly procedures as an alternative method to the expensive and toxic chemicals previously used. Thus, this study was conducted to synthesize and analyse Se NPs using polygonum minus leaves extract. The produced Se NPs were characterized using Field Emission Scanning Electron Microscope (FESEM), UV-Visible Spectroscopy (UV- Vis), and IV measurement to analyse the electrical conductivity. The morphology of the produced Se NPs was in spherical-shape within the diameter range of 60 nm – 90 nm, while the peak of absorbance was at 2-2.5%, showing the low absorbance of Se NPs. Resistance and resistivity of Se NPs showed 338.4 ohm and 16.92 ohm.cm respectively. The electrical conductivity of Se NPs reached a low conductivity which was 0.059 S/cm. This study successfully showed that Se NPs can be produced through green synthesis and having low conductivity for future electrical and electronic applications.
