Laser printing of optically resonant hollow crystalline carbon nanostructures from 1D and 2D metal-organic frameworks

Using a hybrid approach involving a slow diffusion method to synthesize 1D and 2D MOFs followed by their treatment with femtosecond infrared laser radiation, we generated 100-600 nm well-defined hollow spheres and hemispheres of graphite. This ultra-fast technique extends the library of shapes of crystalline MOF derivatives appropriate for all-dielectric nanophotonics. Using a femtosecond laser radiation, we generated hollow carbon spheres and hemispheres from 1D and 2D MOFs.
