Abstract Accurate and clear bioimaging is crucial in the field of medical diagnosis. High‐quality bioimaging requires to avoid the effects of ambient light as well as the absorption of biological tissues. Nearinfrared (NIR) narrowband detectors located at wavelength from 650 to 900 nm can meet these requirements; thus, they are the potential solution. In this work, we construct a filter‐free and self‐power NIR narrowband photodetector based on the structure of n‐CdSe/p‐Sb2(S1‐x,Sex)3 heterojunction, and achieve a narrow spectral response at 735 nm with a full width at half‐maximum of 35.3 nm in the detector. Further, the imaging characteristics of the NIR narrowband detector are explored, verifying the ability to narrowband detection and imaging. This filter‐free and self‐power NIR narrowband detector shows considerable promise in real‐life applications.
