Highly sensitive fast-response near-infrared photodetectors based on triple cation Sn-Pb perovskite for pulse oximetry system

Blood oxygen saturation has emerged as a crucial physiological parameter following electrocardiography, respiration, and blood pressure measurements. In this study, high-quality low bandgap triple cation Sn-Pb perovskite films are fabricated, with the preferred orientation and extended light absorpt...
