Morphological, Structural, and Optical Properties of Doped/Codoped ZnO Nanocrystals Film Prepared by Spin Coating Technique and Their Gas Sensing Application

In today’s world of electronics, nanomaterial applications pose a challenge. The spin coating approach was used to create nanostructured ZnO with wurtzite structure in recent study. Antimony doping, aluminum, and antimony codoping 2.0 percent were make these films. impact doped codoped films on structural, optical properties, morphological has been examined using variety characterization approaches. A nanocrystal diameter 20-30 nm discovered XRD (X-ray diffraction). According SEM (scanning electron microscope) scans, the grain size is 80-120 region. use Fourier transform infrared spectroscopy (FTIR) detect elemental elements studied, peak at 400-520 cm-1 identified as ZnO. properties checked, it that antimony-doped larger band gap than Al antimony-codoped This proved may be gas sensors solar cells. response static sensor system based Sb-doped measured compared Al- Sb-codoped presence ethanol vapor.
