High-performance photodetectors (PDs) find potential applications in extensive areas such as self-driving vehicles, resource monitoring, imaging, communication, etc. However, low sensitivity, slow response speed, and poor air stability have limited their application. In this work, we construct an air stable one-dimensional ternary transition metal chalcogenide Nb2Pd3Se8-based PD that has high sensitivity and fast response and is polarization-sensitive. The Nb2Pd3Se8 nanowire-based PD shows a maximum responsivity of 47 A W−1, a detectivity of 3.28 × 1011 Jones, and a response time of 50–65 µs under 520 nm laser illumination. In addition, the 1D PD shows polarization-sensitivity with a 0.47 anisotropic ratio. This performance paves way to construct robust air stable PDs with high detectivity and high responsivity using one-dimensional Nb2Pd3Se8-based nanostructures.
