Abstract To study the vacancy mechanism of In 2 O 3 , we apply first‐principles method to influence on structural stability, electronic and optical properties rhombohedral . Two vacancies: In‐vacancy (V ‐In ) O‐vacancy ‐O are considered here. The calculated results show that with thermodynamic dynamical stabilities based formation energy phonon dispersion. particular, has better stability in comparison O‐vacancy. Importantly, exhibits ultraviolet properties. However, two vacancies lead peak migration from region visible light region. Furthermore, it is found band gap 1.07 eV, which wider than parent (0.841 eV). Naturally, wide removed atom aggravates difficulty interaction between conduction valence near Fermi level. On contrary, shows metallic behavior because enhances

The advancement of industry and the hastening urbanization have led to serious problems associated with emanation various harmful lethal gases, which are a threat humankind. Therefore, fabrication highly sensitive selective sensors for monitoring these gases is desirable. Due its stability, sensitivity, selectivity in general environment, indium oxide (In2O3) has attracted considerable attention gas sensing. Thus, current review discusses latest research made over last five years on In2O3-based sensors. influence environmental pollutants, such as VOCs, NOX, CO, O3, NH3, SO2 environment human life were discussed. Among synthesis methods, hydrothermal approach been most used preparation based In2O3. drawbacks challenges linked In2O3 (5) years, showed that functioning at higher temperatures. This lack commercialization because reliability issues long-term stability drift. So far, noble metals doped-In2O3 shown promising advantages room temperature operation, could be useful reaching next generation intelligent from micro/nanomaterials era self-powered, artificially system their integration smartphones. Bluetooth modules can make it feasible wirelessly monitor concentration different without need an external power source transmit information via smartphone. would further suitable wireless signal detection, Internet Things, data processing, particularly machine learning, aid
