An organic–inorganic hybrid perovskite material [Me3NCMe3]GaCl4 exhibits a two-step off–on–off SHG response with a large temperature interval†
Abstract
Reaction of a quaternary ammonium salt with GaCl3 in concentrated HCl aqueous solution led to an organic–inorganic hybrid perovskite material [Me3NCMe3][GaCl4] (1), which shows a two-step off–on–off second harmonic generation (SHG) response with a rapid and large temperature interval.
