Description
The high energy ball milling technique was employed to synthesise the undoped ZnO, 5% Co and In single doped and Co-In double doped ZnO nanoparticles. The x-ray diffraction (XRD) was used to probe the structural properties. It was found that the difraction pattern for In-ZnO nanoparticles display an additional peak which was associated with In+3 dopant. Now, incorparating Co and In into ZnO nanoparticles resulted in the reduction of the avarage grain sizes. The scanning electron microscopy (SEM) images shows that the nanoparticles have a spherical shape. The kenosistec station equipment was used to characterise the prepared samples for gas sensing application. Ammonia (NH3) gas is being probed in the present work. In all the diffraction patterns observed, the undoped and double doped ZnO nanoparticles are being favoured at a temperature range 200 – 350 ⁰C.
