Photodetector Based on CsPbBr<sub>3</sub>/Cs<sub>4</sub>PbBr<sub>6</sub> Composite Nanocrystals with High Detectivity
High-quality, all-inorganic CsPbBr<sub>3</sub>/Cs<sub>4</sub>PbBr<sub>6</sub> composite perovskite nanocrystals (NCs) were obtained with all-solution-processing at room temperature, and a photodetector (PD) with high detectivity was realized based on CsPbBr<sub...
