PbSrSiO₄: a new ultraviolet nonlinear optical material with a strong second harmonic generation response and moderate birefringence

Abstract

Introduction of Pb²⁺ cations in silicate systems generates a new compound, PbSrSiO₄, which exhibits excellent properties, including a strong second harmonic generation response (∼5.8 × KDP), a short UV cut-off edge (240 nm) and moderate birefringence (0.053@1064 nm). These results suggest that PbSrSiO₄ is a promising UV NLO material.
