Linear optical afterglow and nonlinear optical harmonic generation from chiral tin(iv) halides: the role of lattice distortions

state for phosphorescent emission. These distinct linear and nonlinear optical properties denote the important role that the lattice distortion plays in tuning the optical properties of low-dimensional HOMHs, and offer a promising perspective of 0D tin(IV) halides for applications in optoelectronic materials and devices.
