Plasmon‐Enhanced Second‐Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures

ABSTRACT The intrinsically weak nonlinear optical response of existing materials, further constrained by symmetry‐forbidden second‐order processes in centrosymmetric media, severely limits efficient frequency conversion in deeply subwavelength, ultrathin volumes. Addressing this...

Seeded Growth of Plasmonic Core‐Shell NU‐1000 NanoMOFs With Intracellular Optical Readout

ABSTRACT Plasmonic gold bipyramids (AuBipy) encapsulated within a NU‐1000 metal‐organic framework (MOF) create robust core–shell nanocomposites. These porous nanoassemblies combine the near‐infrared (NIR) plasmonic resonance of the metallic core with the intrinsic photoluminescen...
