Synthesis and Modulation of Visible-Bandgap Semiconductor Nanowires and their Optical Sensor Application

Abstract

The work successfully demonstrated syntheses and characterization of CdSxSe1-x (x = 0, 0.25, 0.5, 0.75, 1) nanowires. The high quality crystallinity and optical properties of these nanowires were demonstrated for the potential optical sensor applications. The energy bandgap was also modulated by making solid solutions (CdSxSe1-x) in the spectral region from 1.74 eV to 2.45 eV as a function of the sulfur content. The photo-detector using CdSxSe1-x nanowires demonstrated well defined spectral responses depending on the bandgap energy of CdSxSe1-x nanowires.
