Description

Highlights: • Enhanced birefringence and SHG response of Pb2B5O9Cl comparison with its isostructural M2B5O9Cl. • The enhancement originates from the covalent interaction of Pb and O atoms. • The interaction of Pb–O reduces the bandgap comparison with its isostructural M2B5O9Cl. - Abstract: It is important to investigate the electronic structures and optical properties of the UV NLO compound containing lone-pairs electrons, aiming to make a subtle balance among relative large SHG response, big birefringence and deep bandgap. In this paper, the electronic structures and optical properties of M2B5O9Cl (M = Sr, Ba, and Pb) have been investigated using the DFT method. The results show that the enhanced birefringence and SHG response are found in Pb2B5O9Cl comparison with that of Sr2B5O9Cl and Ba2B5O9Cl. And the enhanced birefringence and SHG response in Pb2B5O9Cl originate from the covalent interaction between the oxygen and lead atoms
