Metal-organic frameworks are of interest as a good candidate for fabrication of optical devices with widely tunable optical properties. Improving nonlinear properties and the enhancement of SHG make the route to the usage of MOFs for various applications. We demonstrate at the first time a novel approach for the enhancement of the SHG for MOFs. The approach is consisted in the combination of MOFs and silicon nanoparticles. The maximum 10-fold enhancement is demonstrated. The achieved results paves the way for the application of MOFs as a components of perspective nonlinear organic-inorganic nanophotonic devices.
