Abstract

Two rare-earth borate UV NLO crystals, Rb4.1Na2.9SrSc2(B5O10)3 (RNSSBO) and Na4Rb3Sr0.8Sc2.2(B5O10)3 (NRSSBO), featuring [B5O10] groups and [Sc/SrO6] octahedra, were identified via rational elemental substitution. Notably, RNSSBO exhibits a UV cutoff edge at 192 nm, a wide bandgap of 5.49 eV, high thermal stability, and second harmonic generation comparable to KDP.
