“…An improved monodispersity of nanoparticles obtained from bidentate acetylacetonate precursors in comparison to NPs synthesized from monodentate ligands supports this approach. 24,35 However, as the thermal decomposition of Zn(acac) 2 and Al(acac) 3 differs, 36 it is important to characterize and verify the formation of monomers, the stabilization mechanism of the ZnO:Al nanoparticles, and the doping of ZnO with Al.…”

Al-doped ZnO nanoparticles are synthesized by means of a heating up solution based thermal decomposition method. The synthesis involves a reaction of zinc acetylacetonate hydrate, aluminium acetylacetonate and 1,2-hexadecanediol in the presence of oleic acid and oleyl amine. A proposed reaction mechanism from reagents to monomers is corroborated by analysis of the evolving gases using headspace GC-MS analysis. The Al-doped ZnO nanoparticles synthesized are dynamically stabilized by adsorbed oleate ions, after deprotonation of oleic acid by oleyl amine, as was found by NOESY proton NMR and complementary FTIR spectroscopy. Precession electron diffraction shows a simultaneous increase in lattice parameters with Al concentration. This, together with HAADF-STEM and EDX maps, indicates the incorporation of Al into the ZnO nanoparticles. By the combination of complementary characterization methods during all stages of the synthesis, it is concluded that Al is incorporated into the ZnO wurtzite lattice as a dopant

“…22 A pathway of this decomposition synthesis was studied by Pinna et al 23 and Ambrozic et al 24 for monometal oxides including iron oxide and zinc oxide. We monitor the proposed pathway for doped ZnO:Al nanoparticles by identifying the decomposition products that evolve during the synthesis process.…”

“…Different synthesis methods, such as solid-state reaction [18], coprecipitation [19][20][21], sol-gel [22][23][24], hydrothermal [25][26][27], pyrosol [28,29], microemulsion [30][31][32], combustion [13], and electrochemical methods [33,34] have been used in order to obtain the europium-doped zinc oxide nanoparticles. The precipitation/coprecipitation method, as compared to other chemical or physical methods, is an inexpensive method which allows the synthesis of a wide range of nanoparticles with different and controlled sizes and shapes [19,20,[35][36][37].…”

A valence states approach for luminescence enhancement by low dopant concentration in Eu-doped ZnO nanoparticles

et al. 2015

The paper presents a simple, reproducible, controllable, and direct wet chemical synthesis method for Zn 1-x Eu x O nanoparticles. The full understanding of decomposition mechanism of the as-obtained oxalate precipitate was achieved based on the thermal analysis correlated with the evolved gas analysis and FTIR spectroscopy. The structure, morphology, and optical luminescent properties of the Zn 1-x Eu x O nanoparticles have been investigated by X-ray diffraction, Raman spectroscopy, HRTEM, SAED, XPS, and PL. The XRD studies reveal the formation of a hexagonal wurtzite-type structure. The presence of Eu 2 O 3 cubic structure can be observed up to 0.5 mol% Eu, suggesting that the solubility of the divalent or trivalent Eu into the ZnO lattice is limited. The formation of Eu 2 O 3 secondary phase at higher Eu concentration is sustained by Raman spectroscopy and XPS, as well. The TEM investigations of the Eu-doped ZnO samples illustrate the presence of aggregates with different shapes and dimensions formed by agglomerated spherical and polyhedral nanoparticles with sizes ranging from 20 to 120 nm. The effect of europium concentration on the structural and morphological characteristics, as well as on the luminescent properties was studied with special emphasis on the europium chemical states-Eu 2? and Eu 3? . The PL measurements sustain the presence of both divalent and trivalent europium ions into the ZnO host lattice and, at the same time, an increase of its defects density induced by the dopant presence.

“…In the former case the direct formation of the Zn-OH species can take place, whereas in the latter case the unstable ZnOBu intermediate forms, which subsequently converts into the ZnOH species and sodium methacrylate. The ZnOH species represents the monomeric units for the nucleation of ZnO nanocrystals, which proceeds through the formation of Zn-O-Zn bonds via the condensation reaction [22,23].…”
