Abstrakt: This work studies the impact of positioning nickel nanoparticles (Ni‐NPs) on the surface of doped (P84‐PEO) nanocomposite films by using an ultra‐uniform magnetic field as a model for positioning magnetic NPs inside a polymeric matrix. This process is used to achieve desired and adjustable optoelectronic properties and to obtain new optical and electrical characteristics. P84‐PEO copolymer doped with Ni‐NPs exposed to a 450 mT magnetic field during the preparation give rise to a momentous increase in surface roughness, surface reactivity, and modified optical parameters, besides forming Ni oxides on the surface. Based on X‐ray photoelectron spectroscopy experiments, substantial extra shifts occurred in the binding energies of photo‐excited electrons from the O1s and C1s core levels. Additionally, the deconvoluted O1s spectra displays an additional photoelectron peak at 530.0 eV, most likely attributed to oxidized Ni‐NPs at the surface. Moreover, optical and structural properties were studied using UV–Vis and PL spectroscopy and X‐ray diffraction. [ABSTRACT FROM AUTHOR]
