This thesis focuses on advanced 2D perovskite nanomaterials by engineering band structures for optoelectronic device applications, including the realization of 2D hybrid perovskite p-n junctions with strong charge depletion, surface functionalization of 2D perovskites, and mixed-halide perovskite nanoplatelets with a gradient bandgap. We demonstrate that the engineered band structures of 2D perovskites benefit the performance improvement of the perovskite nano-devices, such as photodiodes, photodetectors and X-ray detectors.
