A-site cation manipulation of exemplary second harmonic generation response and optical anisotropy in rare-earth borates.

ABSTRACT: Ultraviolet nonlinear optical (UV NLO) materials have garnered significant interest for their prospective applications in advanced laser technologies. However, tailoring the desired structure in these materials remains a formidable challenge. Here, we propose a simple yet effective strategy for synthesizing rare-earth borates, K _x Na_3-x La₂B₃O₉ (x = 2-3), by manipulating the A-site cations to induce structural evolution. Notably, K _x Na_3-x La₂B₃O₉ undergoes a phase transition from the Pnc2 to the Amm2 space group by adjusting the K⁺ content to reach x = 2.6. Moreover, the target compounds exhibit strong phase-matchi
