The influence of surface plasmons on the optical properties of composite films on the basis of poly(3-hexylthiophene), fullerene derivatives, and nickel nanoparticles

Abstract

It is shown that a previously discovered effect of the introduction of Ni nanoparticles into films on the basis of poly(3-hexylthiophene) and fullerene derivatives (P3HT: [60]PCBM: Ni), which consists in increasing the light absorption and photoluminescence quenching in the spectral range from 400 to 620 nm, can be theoretically explained as being a result of the influence of surface plasmon resonance of Ni nanoparticles on the optical properties of P3HT: [60]PCBM: Ni composite films.
