Abstract

A new beryllium-free deep-UV transparent NLO crystal Li(H₂O)₂Sc(SO₄)₂ features a two-dimensional [Sc(SO₄)₂] framework consisting of twisted [Sc₃S₄O₉] units decorated by [LiO₂(H₂O)₂] groups into a unique layer. Remarkably, Li(H₂O)₂Sc(SO₄)₂ exhibits a phase-matching SHG response of 0.7 × KDP and a deep-UV cutoff edge below 190 nm.
