“…Various pieces of literature reporting magnetic properties of Zn 1− x Mn x O NPs result from the impact of the synthesis method on: the heterogeneous distribution of Mn 2+ ions in the ZnO crystalline lattice (e.g., formation of clusters [ 31 ]), the precipitation of foreign phases [ 33 – 34 ], the stoichiometry; the presence of oxygen vacancies [ 35 – 36 ], and defects of the crystalline lattice. When the synthesis or calcination of Zn 1− x Mn x O was carried out in an oxidising environment and the absence of foreign phases was observed, the obtained material exhibited paramagnetic properties [ 29 , 33 , 37 ]. Whereas, when Zn 1− x Mn x O was synthesised or calcinated for too long or at an overly high temperature, in an oxidising atmosphere, foreign phases in the form of MnO, MnO 2, Mn 2 O, Mn 3 O 4 , as well as products of the reaction of ZnO with Mn x O y such as ZnMnO 3 and ZnMn 2 O 4 were precipitated in the material.…”

SummaryMn-doped zinc oxide nanoparticles were prepared by using the microwave solvothermal synthesis (MSS) technique. The nanoparticles were produced from a solution of zinc acetate dihydrate and manganese(II) acetate tetrahydrate using ethylene glycol as solvent. The content of Mn2+ in Zn1− xMnxO ranged from 1 to 25 mol %. The following properties of the nanostructures were investigated: skeleton density, specific surface area (SSA), phase purity (XRD), lattice parameters, dopant content, average particle size, crystallite size distribution, morphology. The average particle size of Zn1− xMnxO was determined using Scherrer’s formula, the Nanopowder XRD Processor Demo web application and by converting the specific surface area results. X-ray diffraction of synthesized samples shows a single-phase wurtzite crystal structure of ZnO without any indication of additional phases. Spherical Zn1− xMnxO particles were obtained with monocrystalline structure and average particle sizes from 17 to 30 nm depending on the content of dopant. SEM images showed an impact of the dopant concentration on the morphology of the nanoparticles.

“…Among many effective methods developed to produce nanopowders, microwave-assisted synthesis was first developed in 1985 and has quickly become a major area of study. Since microwave radiations were discovered, these have been widely utilized for synthetic chemistry in order to activate chemical reactions more rapidly and homogeneously [25][26][27][28][29]. Moreover, a self-combustion reaction assisted with microwave is extremely suitable for preparation of perovskite nanomaterials due to notable advantages such as simple and convenient experimental set-up, extremely time, and energy saving, as well as offering homogeneous product [30][31][32].…”

LaMnO3 (LMO) nanopowder was synthesized by the microwave combustion method using glycine and nitrate salts of La and Mn as precursors. The as-prepared LMO powder was pressed at high pressure and annealed at 1000°C for 8 hours to make a target for thin film deposition. The structural and elemental analysis was obtained by X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS). Thin films of LMO were fabricated using pulsed electron deposition (PED) at room temperature. The effects of discharge voltage and oxygen/argon flux ratio on the produced thin films were studied. The study shows that stoichiometry and structure of the target was preserved well in the thin films prepared with a discharge voltage from 14 to 15 kV, while the oxygen/nitrogen flux ratio did not show a clear effect on the quality of thin films.

Zinc oxide (ZnO) is a multifunctional material due to its exceptional physicochemical properties and broad usefulness. The special properties resulting from the reduction of the material size from the macro scale to the nano scale has made the application of ZnO nanomaterials (ZnO NMs) more popular in numerous consumer products. In recent years, particular attention has been drawn to the development of various methods of ZnO NMs synthesis, which above all meet the requirements of the green chemistry approach. The application of the microwave heating technology when obtaining ZnO NMs enables the development of new methods of syntheses, which are characterised by, among others, the possibility to control the properties, repeatability, reproducibility, short synthesis duration, low price, purity, and fulfilment of the eco-friendly approach criterion. The dynamic development of materials engineering is the reason why it is necessary to obtain ZnO NMs with strictly defined properties. The present review aims to discuss the state of the art regarding the microwave synthesis of undoped and doped ZnO NMs. The first part of the review presents the properties of ZnO and new applications of ZnO NMs. Subsequently, the properties of microwave heating are discussed and compared with conventional heating and areas of application are presented. The final part of the paper presents reactants, parameters of processes, and the morphology of products, with a division of the microwave synthesis of ZnO NMs into three primary groups, namely hydrothermal, solvothermal, and hybrid methods.
