In recent years, the non-linear optical (NLO) materials have attracted considerable interest because of their new scientific phenomena and potential applications in photonic
technologies.
The development of photonic and optoelectronic technologies rely heavily on the growth of NLO materials with high non-linear optical responses and the development of novel and more efficient materials [1–6].
As an important class of low-dimensional hybrid materials, organic–inorganic perovskite-like family of the type Rx- MyXz (where R is protonated amine,Mis a metal, and X is a
halide) has received considerable interest in the past decades.
In this case, the structures of halogenobismuthates(III) with organic cations, a new group of ferroic crystals, are best described as molecular-ionic, organic inorganic hybrid materials.
