A facile synthesis of two new IR optical perovskites based on 1,4-diazabicyclo[2,2,2]octane with high laser damage threshold

Abstract

The main commercial infrared nonlinear optical (IR NLO) crystals, typically, AgGaS2, have some inherent disadvantages, for example, low laser damage threshold (LDT) or relatively poor stability, which limit their wide application. Here, we discover two new IR optical perovskites based on 1,4-diazabicyclo[2,2,2]octane, namely, (H2dabco)(PbCl3)2 (1) and (H2dabco)(H2PbBr6)·H2O (2). 1 and 2 crystallize in the noncentrosymmetric space group P43212 and P63mc, respectively, displaying broad transparent range with high transmission. Especially, compound 2 exhibits a moderate SHG response of 1.8 times that of KH2PO4 (KDP) at 1064 nm with high laser-induced damage threshold of 328.8 MW cm –2, indicating it is a new promising NLO material.
