| dc.description.abstract | This paper presents the utilization of ethylene glycol monomethyl ether (EGME) during the synthesis of ZnO and La:ZnO with two tasks as a solvent and a fuel source within the gel combustion technique. The use of EGME for this purpose provides one-step production of the nanoparticles (NPs) and saves a considerable amount of time. The detailed characterization of the nanoparticles was carried out by X-ray diffractometer (XRD) scanning electron microscope (SEM) particle size analyzer Fourier transform infrared spectroscopy (FTIR) X-ray photoelectron spectroscopy (XPS) photoluminescence (PL) and Vector Network Analyzer (VNA) measurements respectively. The NPs exhibited a hexagonal wurtzite structure with good crystallinity and a porous spongy morphology. The photoluminescence emission maxima of the synthesized NPs appeared at 500 560 and 676 nm upon excitation by the 372 nm of excitation. La:ZnO NPs showed significantly better photoluminescent characteristics than La-free ZnO forms. When excited at the same wavelength La-free ZnO 3% and 7% La:ZnO exhibited 92 45 and 35 μs average decay times respectively. Finally the microwave properties of the relative complex permittivity and permeability characteristics were also investigated and discussed in detail which were derived from the scattering parameters of S<inf>11</inf> and S<inf>21</inf> in the X band regime. © 2024 Elsevier B.V.
