AbstractDefect tolerance is a critical enabling factor for efficient lead-halide perovskite materials, but the current understanding is primarily on band-edge (cold) carriers, with significant debate over whether hot carriers can also exhibit defect tolerance. Here, this important gap in the field is addressed by investigating how intentionally-introduced traps affect hot carrier relaxation in CsPbX3 nanocrystals (X = Br, I, or mixture).

(9−11) One of the key limitations of LnNPs is their low absorption cross-section, with molar absorption coefficients of lanthanide ions rarely exceeding 1 M–1 cm–1.
