Defect Engineering in Silver-Based Bimetallic Semiconductors: Recent Advances and Future Perspective.

Since the mid-20th century, the interaction between light and inorganic semiconductors plays not only a key role in numerous fascinating phenomena but also provides the physical foundations for the development of many modern technologies focused on health, environmental, and energy solutions. Among these materials, silver-based bimetallic semiconductors have garnered attention due to their enhanced functional properties, which are controlled by the presence and distribution of structural and electronic defects. These defects directly impact key physicochemical properties, making them essential for the development of materials with improved functionalities. Modifying synthetic and postsynthetic parameters is crucial for controlling the type, density, and distribution of these defects in materials. However, achieving precise control of these defects remains a challenge and requires a deeper understanding of the relationship between synthetic conditions and defect formation. This work provides a comprehensive review of how modifications in synthesis methods influence material properties, with a particular focus on understanding their impact on material defects. Specifically, this study examines silver-based bimetallic semiconductors, including Ag
