Abstract

The first metal nitrate fluoride nonlinear optical material, Pb₂(NO₃)₂(H₂O)F₂, was synthesized with the largest second harmonic generation (SHG) effect (12 × KH₂PO₄) among nitrates. Theoretical calculations revealed the synergistic effect of [NO₃]⁻, lone pair electrons in Pb²⁺, and F⁻ for the SHG effect. The F⁻ also promoted the blue-shift of the ultraviolet cut-off edge.
