摘　　要：Exciton diffusion lengths reaching the micrometer length scale have long been desired in solution-processed semiconductors but have remained unattainable using conventional materials to date.Now halide perovskite nanocrystal films show unprecedented exciton migration with diffusion lengths approaching 1μm owing to the efficient combination of radiative and nonradiative energy transfer.
