Abstract Crystalline porous metal–organic frameworks (MOFs) with nanometer‐sized void spaces, large surface areas and ordered reticular motifs have offered a platform for achieving disruptive successes in divisional fields. Great progress exploring the linear nonlinear optical features of MOFs has been achieved, yet third‐order nonlinearities two‐dimensional (2D) rarely studied. Here, broadband amplitude modification phase shift are demonstrated few‐layer nickel‐ p ‐benzenedicarboxylic acid...
Abstract MXene, as a novel 2D crystal material, possessing tunable bandgap, low optical attenuation and broadband nonlinear responses that may promote the fabrications of advanced electro-photonics devices has gathered remarkable attention recently.
