Aspect Ratio and Quantum Confinement Tunable Giant Two-Photon Absorption from 1D CsPbI3 Perovskite Nanorods
{{output}}
Herein, we investigate the influence of aspect ratio and quantum confinement on the single-photon (σ1) and two-photon absorption cross-section (σ2) for perovskite CsPbI3 nanorod (NR). Notably, experimentally measured data show extremely high σ2 for CsPbI3 N... ...
