Abstract

The thin films with embedded identical spheroidal nanoparticles (NPs) are studied in order to derive conditions of configurational resonances. These resonances are determined by the film morphology. The average volume fraction, distribution across the film thickness, shape, and orientation of NPs are chosen as control parameters of the film morphology to be varied. Numerically calculating the light absorption by the film, obtained dependences of absorption intensity at a fixed frequency are represented by contour map for the absorption as a function of two variables—average volume fraction and shape parameter (the aspect ratio of a geometric shape) of NPs. The other parameters, namely, film thickness and volume of each inclusion particle are keeping the same value. The representation allows one to see the domains of the parameters where the absorption by the film is enhanced resonantly and to formulate the optimal conditions for the possible configurational resonance. Hence, the range of the obtained parameters can be used as a recommendation for optimization of technological process of the film fabrication with the desired optical properties.
