Stability and photocurrent enhancement of photodetectors by using core/shell structured CsPbBr/TiO quantum dots and 2D materials.

Ultra-stable CsPbBr perovskite quantum dots (QDs) were prepared, and the performance of the photodetector fabricated from them was enhanced by 2D material incorporation. This multi-component photodetector appears to have good stability in the ambient utilization environment. All inorganic CsPbBr QDs are potential candidates for application in photodetection devices.
