Prospects of controlling the absorption of the cost-effective plasmonic metal nanoparticles (MNPs) Cu and Al using quantum emitters (QEs) are demonstrated semi-analytically. The resulting spectra are compared with the absorption of commonly used noble plasmonic metal nanoparticles Au and Ag under similar conditions. It is observed that Cu and Au-based plasmonic nanoparticles exhibit largely similar exciton–plasmon Fano interaction signatures in addition to their similar spectral regions of operation (lower end of the visible range). Furthermore, the QE-enhanced maximum absorption(Fano maximum) of Cu-based nanohybrids is seen to approach the maximum absorption level of isolated Au MNPs, with decreasing QE-Cuseparation, increasing QE dipole element magnitude, and increasing medium permittivity, in the parameter region considered. This renders Cu based exciton–plasmon nanohybrids as more economical alternatives for Au MNPsand Au-based nanohybrids in absorption-based applications (such as thermo-plasmonic) when stabilized in protective embedding media such as poly (methyl methacrylate) (PMMA).

Briefly describe the importance of this publication: 
In essence, we theoretically demonstrated the prospects of utilizing quantum emitters to dramatically modify the absorption spectra of non-noble plasmonic metal nanoparticles Cu and Alembedded in poly (methyl methacrylate) (PMMA). We compared the resulting absorption spectra to those obtained using the traditional plasmonic metals Au and Ag under similar conditions. Our results reveal prospects of using Cu-based exciton–plasmon nanohybrids as economical alternatives to Au nanoparticles with comparable absorption prowess in absorption-based applications, given suitable methods of synthesis and environmental conditions to support stability.
