| Abstract Scope |
Transparent conductive oxides are essential for technologies such as LEDs, solar cells, and optical detectors. Enhancing their performance requires balancing high optical transparency with electrical conductivity across a broad spectral range. SrxNbO₃ (x < 1) has emerged as a high-performance conductor with transparency in the visible and ultraviolet regimes. A significant limitation in optimizing this material is the influence of A-site (Sr) vacancies on its transport and optical properties. To address this, we have developed a self-consistent method for quantifying Sr vacancies using X-ray fluorescence (XRF). By synthesizing a series of SrNbO₃ samples with known stoichiometry and phase purity (confirmed via X-ray diffraction) we establish internal calibration standards. These custom standards improve accuracy over default XRF references and provide a foundation for analyzing both stoichiometric and disordered compositions, including emerging high-entropy oxides. This work enables precise defect engineering in correlated and disordered oxides, advancing the design of next-generation transparent conductors. |
