摘要
Through sol-gel spin coating technique, pure, (1,3, and 5) wt.% Na-doped ZnO thin film sensors were fabricated and characterized.3 wt.%Na-doped ZnO thin film with porous structure exhibit more oxygen vacancies and carrier density.3%Na-doped ZnO thin film shows enhanced gas sensing performance against 75 ppm of NO2 gas.
