Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...
