TL;DR: Pb-layered perovskite (benzylammonium)2PbCl4 is ferroelectric with semiconducting behaviours, and this finding throws light on the new properties of the hybrid organo-plumbate or stannate compounds and provides a new way to develop new semiconductor ferroelectrics.

TL;DR: A new SHG material, BaNbO(IO(3))(5), has been prepared that exhibits a very large SHG response and is phase-matchable and has high thermal stability and a wide transparent region.

TL;DR: By adjusting the composition x, the bandgap is successfully tuned from previously reported 3.65 eV to as low as 2.74 eV, and the excellent ferroelectricity was kept intact and may contribute to improving the photoelectronic and/or photovoltaic performance of hybrid perovskite-type compounds.

TL;DR: In this paper, the second-order nonlinear optical properties of metal iodates are discussed and a review of metal ion structures and secondorder NLO properties are discussed. But the authors do not consider the effect of the polarizations from both types of the asymmetric units are aligned properly.

TL;DR: Four new potassium vanadyl iodates based on lone-pair-containing IO(3) and second-order Jahn-Teller distorted VO(5) or VO(6) asymmetric units have been successfully synthesized by hydrothermal reactions and display a very strong second-harmonic generation response of about 3.6 × KTP, which is phase matchable.
