Abstract

We have studied the electromagnetic interaction of gain-assisted core–shell nanostructures inside the perovskite environment. The electrostatic model has been developed to modify the dielectric constant of core–shell nanogeometries at nanolevel and studied their impact on the scattering and absorption cross section magnitude. The modification in the shell which is silica has been done by encapsulation of gain media. In core–shell geometry, silver and gold metals were used as core material and silica is used as a shell and gain is introduced into the shell. We have compared the optical cross section of the core–shell nanosphere with and without gain media, and it was observed that the introduction of gain media into the silica layer significantly enhanced the magnitude scattering cross section. This proposed work clearly suggests designing the spacer layer which is a prominent part to fabricate thin-film devices. We have also studied and compared the role of the elliptic core and spherical shell over the spherical core and spherical shell. The investigation of the quality factor (QF) of plasmon resonances under the influence of gain media has also been done and observed that the silver elliptic core and gain-assisted silica shell have the highest QF value.
