Breaking the bottleneck of simultaneously wide band gap and large nonlinear optical coefficient by a 'pore reconstruction' strategy in a salt-inclusion chalcogenide

By applying the “pore reconstruction” strategy, we offer a rare heterologous nanopore salt-inclusion chalcogenide, K3Rb3[K3Cl][Li2Mn4Ga12S27], which breaks the bottleneck of simultaneously wide band gap and large nonlinear optical coefficient.
