A Rare‐Earth Selenite with Unexpectedly Well‐Balanced Ultraviolet Nonlinear Optical Functionality, Sc(HSeO3)3 (Small 19/2023)

Abstract

Rare-Earth Selenites A selenite-based ultraviolet nonlinear optical (UV-NLO) material, Sc(HSeO3)3, reveals remarkably well-balanced UV-NLO properties such as the shortest absorption edge (≈214 nm) among NLO-active selenites, wide band gap (5.28 eV), large phase-matchable second-harmonic generation (SHG) response (5 × KH2PO4 (KDP)), and sufficiently large birefringence (cal. 0.105 @1064 nm). More details can be found in article number 2207709 by Chun-Li Hu, Kang Min Ok, and co-workers.
