“…This emission band can be attributed to electron transitions in intrinsic defects of zirconia nanostructures, which is similar to the literatures. 30 Scanning electron microscope was applied to consider the influences of dosage of TEPA, solvent, and reaction time on the shape of the zirconium dioxide nanostructures. As mentioned, novelty of this work compared to other performed reports is the usage of TEPA as a new precipitator to prepare of zirconium dioxide, without applying any surfactant and capping agent.…”

Zirconia nanostructures have been prepared via a facile precipitation route using Zirconium (IV) oxynitrate hydrate and tetraethylenepentamine (TEPA). Here, TEPA was used as novel precipitator to fabricate zirconia nanostructures. The influence of reaction time, dosage of TEPA, and solvent was also examined to control the shape and particle size. Results of this work indicate that these reaction parameters have important impact on the control of shape and grain size of the zirconia. To characterize the as-synthesized nanostructures, techniques such as X-ray diffraction (XRD), ultraviolet-visible (UV-vis) spectroscopy, energy dispersive X-ray microanalysis (EDX), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and photoluminescence (PL) spectroscopy were applied. In addition, the formation mechanism of zirconia nanostructures was discussed. IntroductionThe nanomaterials have attracted extraordinary research interest due to their unique and advantageous applications in different fields.1,2 One of the nanometerscale oxides is zirconium dioxide. It is reported that zirconia is an important metal oxide because of its unique electrical and optical characteristics 3-5 and also potential usages, including preparation of the transparent optical devices and production of the electrochemical capacitor electrodes, 6 fabrication of fuel cells, 7 and catalysts. 8,9 Zirconia has monoclinic, tetragonal, and cubic crystal forms that are stable at below 1175°C, 1175-2370°C, and 2370-2680°C temperature ranges, respectively.10 So far, various routes have been presented to prepare zirconium dioxide, such as hydrothermal, 11 microwave irradiation, 12 sol-gel, 13 thermal decomposition, 14 precipitation, 15,16 and sonochemical. 17,18 The development of a simple and reproducible approach for preparing nanostructured zirconia is of great importance to the potential investigations of its properties. It has been shown that the particle size and shape of nanomaterials have a great impact on their characteristics. [19][20][21][22][23][24][25] So, exploring suitable methods to prepare zirconia and controlling its morphology and particle size is important and necessary. Herein, the precipitation route is presented to synthesize zirconia nanostructures. Precipitation route is well-known as an appropriate preparation approach for production of various nanomaterials. This route is known as facile, reproducible, and useful preparation approach and presents an advantageous way to the preparation of homogeneous nanostructures. This work is the first successful attempt for the preparation of zirconium dioxide nanostructures using tetraethylenepentamine (TEPA) as precipitator. To go further into the study, the influence of dosage of TEPA, reaction time, and solvent on the shape and particle size of zirconia is examined. ExperimentalZirconium (IV) oxynitrate hydrate (ZN), tetraethylenepentamine (TEPA), ethylenediamine (EN), ethylene glycol (EG), propylene glycol (PG), and meth...

“…The PL and especially PA of zirconia films have been seldom reported [5,6], although PL and PA have been observed in a ZrO 2 sol and nanoparticle systems [7][8][9][10]. It has been proposed for these systems that PL centers are defect centers related to oxygen vacancies and interstitial defects.…”

“…Recently, many oxide materials such as Co 3 O 4 nanocubes, ZrO 2 nanospheres, MgO nanoflakes etc. have also been prepared by a rapid MCM process [21][22][23]. Nanosized particles prepared by using the MCM approach are expected to have a larger surface area, smaller particle size, and greater stability than those obtained by other methods.…”
