A simple solution combustion technique was used to manufacture Gd2O3-ZnO nanocomposite successfully. The presence of different peaks in sample XRD patterns confirms the formation of a Gd2O3-ZnO nanocomposite. According to the Debye-Scherrer formula, the typical crystallite size ranges from 26 to 34 nm. Microstrain and dislocation density both rose from Z1 to Z4, according to thorough microanalysis. A well-organized spongy network with pore sizes ranging from 50 nm to 800 nm was produced, according to the FE-SEM and TEM research. EDS analysis was used to determine the quantitative analyses of the materials. The optical study shows the bandgap of the Z1 to Z4 thin film was varied between the range of 3.20 to 3.25 eV. The sensing nature of Gd2O3-ZnO nanocomposite was thoroughly examined for NO2 at various temperatures and concentrations. Enhanced sensitivity of 24.79% is observed for 60 ppm of NO2 at 200°C for sample Z2. Also, the quick response of 27sec was noted. [ABSTRACT FROM AUTHOR] |
