Nanostructured antimony tin oxide synthesized via chemical precipitation method: its characterization and application in humidity sensing
Abstract
In present investigation we report the synthesis of antimony tin oxide nanoparticles via chemical precipitation method. The synthesized material was characterized using X-ray diffractometer, Scanning Electron Microscope, UV-visible absorption spectroscopy. XRD shows the crystalline nature of the synthesized material and the crystallite size was estimated by using Debye-Scherer equation and its minimum value was 3 nm. Pelletization of synthesized material was done using hydraulic press machine under uniform pressure of 616 MPa. Then the pellets were annealed at 200, 400 and 600{\deg}C. Further each pellet was put in humidity sensing chamber and corresponding variations in resistance with relative humidity (%RH) were measured. The average sensitivity was calculated by taking the average of all sensitivities ranging from 10 to 90% RH. The average sensitivity of the pellet annealed at 600{\deg}C was best among all the sensing pellets and was 2.18 K{\Omega}/%RH. Results were reproducible {\pm}84% after 2 months.
