 Abstract broadband photodetectors, PDs, with low detection limits are important for next generation optoelectronic devices. A new 2D bilayered lead iodide hybrid parafskite, 2IPA, was developed that addresses this challenge. This material has a minimized dark current, excellent electrical properties, and a narrow band gap, making it suitable for detecting both broadband weak lights and X-rays. The resulting high-quality single crystals have high responsivity and significant detectivities, making them ideal for detecting weak UVVS light and X-rays.
