Excerpt

Pb3P2S8 was structurally characterized three decades ago with a second harmonic generation response. In this work, Pb3P2S8 was revisited to investigate its electronic structure via DFT calculations and optical properties by UV-vis measurements, second harmonic generation tests, laser damage threshold tests, and photocurrent measurements. Pb3P2S8 is constructed by [PbS7] polyhedra and [PS4] tetrahedra, which was supported by crystal orbital Hamilton population (COHP) calculations. The electron localization function …
