چکیده
High-quality, all-inorganic CsPbBr3/Cs4PbBr6 composite perovskite nanocrystals (NCs) were obtained with all-solution-processing at room temperature, and a photodetector (PD) high detectivity was realized based on NCs. The (D*) of the proposed PD is 4.24 × 1012 Jones under 532 nm illumination, which among highest levels for PDs In addition, linear dynamic range (LDR) 115 dB 1 V bias also realized. Furthermore, underlying mechanism enhanced performance discussed. Our work might promote preparation high-performance dual-phase nanocrystals.

Low Noise, High Detectivity Photodetectors based on Organic Materials
Organic photodetectors (OPDs) are potentially useful in many applications because of their light weight, flexibility and good form factors. Despite the high detectivities that have been frequently reported for OPDs recently, the application of these OPDs for weak light detection has been rarely demonstrated. In this thesis, low noise, high gain photodetectors based on organic and ZnO nanopartic...
متن کاملSolution-processed hybrid perovskite photodetectors with high detectivity.
Photodetectors capture optical signals with a wide range of incident photon flux density and convert them to electrical signals instantaneously. They have many important applications including imaging, optical communication, remote control, chemical/biological sensing and so on. Currently, GaN, Si and InGaAs photodetectors are used in commercially available products. Here we demonstrate a novel...

Herein, we describe simple, fast and reproducible halide ion exchange reactions in CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) at room temperature. Through the simple adjustment of the halide ion concentration, the photoluminescence of these NCs can be tuned over the entire visible region (425-655 nm). Photodetector devices based on entirely inorganic CsPbI3 NCs are demonstrated for the first tim...

The mid-infrared (MIR) spectral range, pertaining to important applications, such as molecular "fingerprint" imaging, remote sensing, free space telecommunication, and optical radar, is of particular scientific interest and technological importance. However, state-of-the-art materials for MIR detection are limited by intrinsic noise and inconvenient fabrication processes, resulting in high-cost...
