The intensity of dipole and quadrupole mode peaks increased in the optical density spectra after annealing of the hybrid structures at 200°C.…”

“…The usage of plasmonic nanostructures allows to control emission linewidth, peak and intensity of CdSe/ZnS semiconductor quantum dots (Soganci et al ., 2007; Chan et al ., 2009; Ahmed et al ., 2012; Wang et al ., 2015). The electronic structure of amorphous hydrogenated carbon in the thin‐film structures with Au nanoparticles (NPs) (Konshina et al ., 2018; Konshina et al ., 2019) and Ag NPs (Khmelevskaya et al ., 2018; Konshina et al ., 2019; Shcherbinin et al ., 2019; Konshina et al ., 2020; Shmagina et al ., 2020) affects the blue shift and intensity of the plasmon band in the optical density spectra. The intensity of dipole and quadrupole mode peaks increased in the optical density spectra after annealing of the hybrid structures at 200°C.…”

“…The intensity of dipole and quadrupole mode peaks increased in the optical density spectra after annealing of the hybrid structures at 200°C. This fact was connected with the form and size changes of Ag NPs (Shcherbinin et al ., 2019). The effect of excitons–plasmon interaction of semiconductor nanoparticles and amorphous hydrogenated carbon (a‐C:H) with plasmonic nanostructures on the enhancement of their photoluminescence was shown in (Khmelevskaya et al ., 2018; Konshina et al ., 2019; Konshina et al ., 2020).…”

“…Varying morphology of metal island films enables to control the characteristics of localised surface plasmon resonance (LSPR). The variation of LSPR is very important for thin‐film hybrid structures with semiconductor and dielectric materials (Khmelevskaya et al ., 2018; Konshina et al ., 2019; Konshina et al ., 2019; Shcherbinin et al ., 2019; Konshina et al ., 2020; Shmagina et al ., 2020). As known, the optical properties of plasmonic nanoparticles strongly depend on nanostructures morphology.…”
