Nonlinear Optical Perovskites: Halide Perovskites for Nonlinear Optics (Adv. Mater. 3/2020)

Halide perovskites are a promising platform for the construction of nonlinear optical materials in light of their structural diversity, high hyperpolarizability, and bandgap tunability. In article number 1806736, Jialiang Xu, Xian-He Bu, and co-workers review the current state of the art in purely inorganic and in organic–inorganic-hybrid halide perovskites as nonlinear optical materials and discuss their potential for various nonlinear photonic applications.
