“…In the literature many preparative techniques for Cr 2 O 3 nanoparticles are described, including a hard-template pathway with mesoporous silica, 6 hydrothermal reduction, 7,8 solution-combustion synthesis, 9 hydrazine reduction and thermal treatments, 10 urea-assisted homogeneous precipitation, 11,12 mechanochemical processing, 13 supercritical alcohol, 14 laser-induced pyrolysis, 15 sonochemical reaction, 16 microwave plasma, 17 condensation-polymerization process, 18 precipitation-gelation reaction 19 and gas condensation. 20 For most of them a large particle size distribution, low yields or important costs are the major disadvantages.…”

“…This is due to the grain barrier effects which occur at nanosize which play an important role on the dielectric properties of the materials, and they exhibit novel catalytic, optical, magnetic and electrical properties relative to those of the bulk materials [1][2][3][4][5]. The regular improvement in display market is extending its study on the next-generation display devices such as organic light-emitting diode (OLED) or flexible display [6,7].…”

Zinc-doped yttrium oxide nanopowders of various doping concentrations have been successfully synthesized by simple methods like sol-gel, solvothermal and wetchemical methods. Structural property is analysed by X-ray powder diffraction (XRD). The presence of elements is confirmed by FTIR studies. Conductivity and dielectric behaviour of the samples are analysed by impedance spectroscopy. The effects of doping concentration and method of preparation on the crystallinity, the dielectric constant and the electrical properties of zinc-doped Y 2 O 3 nanomaterials are investigated and presented in this paper. XRD analysis shows the crystalline nature of the samples except the one prepared by solvothermal method. Also, the same sample is found to have more conductivity in the order of 5.04×10 −7 Scm −1 when compared with the samples prepared by other methods and of different doping concentration.

“…[7][8][9][10][11] Cr 2 O 3 nanoparticles have been prepared and characterized by several researchers. [12][13][14] In our previous work, we studied the thermal and structural properties of gamma-irradiated PVA/poly(ethylene glycol) thin film. 15 It is found that the stabilization of PVA using both different additives and irradiation is required.…”

Nanosized chromium oxide Cr 2 O 3 was prepared and mixed with polyvinyl alcohol (PVA) to produce nanocomposite films. X-ray diffraction (XRD) and transmission electron microscopy were performed to study the crystallinity and size of nano-Cr 2 O 3 . Based on the results, the average particle size of the Cr 2 O 3 was found to be 29 nm. The effects of nanosized chromium oxide Cr 2 O 3 concentration and gamma dose on the structural and optical properties of PVA have been studied. The resultant effect of Cr 2 O 3 concentration on the properties of PVA has been investigated using XRD and UV spectroscopy. The results reveal that the addition of Cr 2 O 3 to PVA up to 0.80% leads to a more compact structure of PVA, resulted in an improvement in the isotropic nature of the polymer samples due to the increase in the refractive index. In addition, the effect of gamma irradiation on the 0.50% Cr 2 O 3 /PVA nanocomposite has been investigated. Samples from the 0.50% Cr 2 O 3 nanocomposite were irradiated with gamma doses in the range 200-1 kGy. It is found that the irradiation in the dose range 200-800 Gy causes cross-linking that increases the amorphous regions and gives polymer resilience. C
