Two-dimensional (2D) nonlinear optical monolayers are brilliant candidates for future nanoscale laser devices, typically within the deep ultraviolet(DUV) region. In our work, we propose a material template-optimized design strategy to...
A new sulfate Li8NaRb3(SO4)6·2H2O exhibits a short cutoff edge below λ < 190 nm and has a moderate second-harmonic generation response in type-I phase-matchable behavior.
