“…The SERS has been observed for In as well 52. A plasma peak in the spectrum of inelastic electron loss was found at 5.2 eV in a dielectric zeolite matrix containing as small as 8‐atoms indium clusters 53. The observation of the Mie resonances in In MNPs within InN by the thermally detected optical absorption (TDOA) technique in the spectral range 0.7–1.0 eV has been numerically reported 29, 43–46.…”

Optical properties of the nanocomposites are controlled by localized plasmons (Mie resonances) in the MNPs. The basic properties of the nanocomposites have been studied using InN/In with In clusters formed both spontaneously and by the periodic deposition of In insertions. In the specially designed nanocomposites, the spots of intense cathodoluminescence are strongly correlated with the agglomerations of the In MNPs due to plasmon-induced enhancement. Furthermore, a strong difference is discovered between the onsets of thermally detected absorption and photocurrent. This feature is a key to distinguish InN/In from pure InN. To simulate the plasmonic effects in the nanocomposites a model has been proposed, which considers the clusters as spheroids of random shapes and orientations. The calculated dependences are in reasonable agreement with obtained optical data.
