Circularly polarized luminescence and nonlinear optical harmonic generation based on chiral zinc halides

Abstract

Chiral hybrid metal halides have grabbed extensive attention in linear and nonlinear chiroptics. Herein, 0D chiral zinc halides, (R-/S-2-MP)ZnCl₄, have been fabricated, which demonstrate high efficiency second-order nonlinear optical responses. Incorporating Sb³⁺ into the chiral zinc halide matrix triggers the circularly polarized luminescence effectively with a balance between quantum yield and luminescence dissymmetry factor.
