Abstract Studies of the nonlinear optical phenomena that describe light‐matter interactions in 2D crystalline materials have promoted a diverse range photonic applications. MXene, as recently developed new material, has attracted considerable attention because its graphene‐like but highly tunable and tailorable electronic/optical properties. In this study, we systematically characterize response MXene Ti 3 C 2 T x nanosheets over spectral 800 nm to 1800 nm. A large effective absorption...
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.
