Researchers suggest a simple yet coherent approach of harnessing conspicuously enhanced upconversion luminescence (UCL) from the NIR-to-visible upconversion nanoparticles (UCNPs) by utilizing the disordered array of plasmonic metal NPs (DANPs) on the dielectric layer supported by a metallic back reflector. The approach focuses on the systematic design of the DANPs with an optimized spatial order to obtain the strongest UCL in the MIM structure. The designed platform shows outstanding optical and photonic performances compared to counterpart platforms with 2D periodically ordered arrays of NPs (OANPs) .
