AgEuPS4: Unlocking the CentrosymmetricShackle of Rare-Earth Thiophosphates via Microscopic Distortion Cascadingfor Enhanced Second-Harmonic Generation Response

Abstract Breaking the rigid centrosymmetric (CS) shackles of rare-earth thiophosphates remains a significant challenge for designing high-performance mid-to-far-infrared (MFIR) nonlinear optical (NLO) materials. Herein, using the CS LiEuPS4 (I41/acd) as the structural template, a...
