The fabrication of Au-C60 nanocomposite thin films by incorporating nanosized Au into a fullerene C60 matrix via thermal co-deposition technique has been successfully achieved. These films were irradiated by 120 keV Ar and 150 MeV Ag ion beam using two different low-energy and high-energy ion accelerators. The optical spectra of pristine and irradiated thin films were observed in the wavelength region from 300 to 1000 nm, indicating a minor blue shift in wavelength at higher fluences for the low-energy ion irradiation but no significant changes in high-energy ion irradiation. This behavior of optical response by Au nanoparticles under irradiation is explained by Maxwell Garnett’s effective medium theory. The shift in SPR bands is explained with the help of induced interaction between particles due to ion irradiation. To understand the disorders and defects induced in the fullerene C60 matrix due to ion irradiation, Raman Spectroscopy measurements were done before and after irradiation in case of low-energy and high-energy ion beams. The transformation of fullerene C60 into amorphous carbon has been seen in both cases.

Despite progress, a persistent challenge remains in expanding the effective absorption bandwidth (EAB) for microwave absorbers based on MOFs. To solve the above problems, in this work, NiFe@CN nanocomposite consisting of nickel–iron alloy nanoparticles (NiFe alloy NPs) embedded into nitrogen-doped carbon nanotubes (NCNTs) were fabricated utilizing a flexible two-step method, including co-precipitation and chemical vapor deposition, where the synthesized precursor NiFe Prussian blue analogs (NiFe-PBA) served as the self-sacrificed template and dicyandiamide (DCDA) served as carbon source. By tailoring the mass ratio of DCDA to NiFe-PBA, the morphology of synthesized NiFe@CN nanocomposites can be precisely controlled to create more tubular structures. These structure features enable NiFe@CN nanocomposites to acquire a synergistic effect of interfacial polarization, defect dipole polarization, conduction loss, eddy current loss, and magnetic resonance, which leads to enhanced dielectric loss, optimized impedance matching, and intense attenuation capability. As a result, the NiFe@CN nanocomposites exhibit excellent microwave absorption performance. At a thickness of 2.04 mm, the minimum reflection loss (RLmin) is − 54.09 dB at 13.41 GHz, and the EAB is 5.78 GHz.

Moreover, a notable decrease in non-radiative recombination has been observed, resulting in a substantial improvement in device stability. The incorporation of 0.04 RbBr into CsPbBr3 leads to a decrease in the hysteresis index of PSCs to 0.016.
