ABSTRACTIn this paper, the authors have reported the structural and photoluminescence (PL) studies of pure and nickel (Ni) doped zinc oxide (ZnO) nanoparticles synthesized by the solution combustion method. The structural, morphological and optical studies are carried out by powder x-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM) and PL spectra, respectively. The XRD pattern indicates that the prepared particles are in hexagonal wurtzite structure with the average crystalline size is around 35-50nm. Room temperature PL shows the near band edge related emission and the results are related several intrinsic defects in the ZnO nanoparticles.

In this work, a novel route is discussed to produce in one step ZnO/Burkeite powders by the modified solution combustion method. The ZnO particles enhance the photocatalytic activity in the degradation of Rhodamine B, in which Burkeite mineral acts as a support due to the pH-dependent morphology of the particle aggregates of the as-synthesized powders. The X-ray diffraction (XRD) characterization shows the presence of a heterostructure: ZnO/Burkeite. The Scanning Electron Microscopy (SEM) image shows a morphological dependence with the pH of the solution used for the synthesis. The results show that the system with the highest degradation (92.4%) corresponds to the case in which ZnO/Burkeite heterostructure was synthesized with a pH 11.

CdSiO3: Ce3+ (1-11mol %) nanophosphors were prepared by low temperature solution combustion method using Oxalyl di-hydrazine (ODH) as fuel. The final products were well characterized by PXRD and SEM. The optical properties of the nanophosphors were investigated by Photoluminescence studies. PXRD results evident that CdSiO3 phosphor shows pure single monoclinic structure. The average crystallite size was calculated using Debye – Scherer’s formula and was found to be in the range of 30-40 nm. The SEM micrographs show phosphors with high porosity and irregular shaped particles. Photoluminescence peaks observed at 454, 563 and 679 nm under 397 nm excitation was due to transition from 5d state to the 2F5/2 and 2F7/2 components of the ground state of Ce3+ in CdSiO3 host material. CdSiO3:Ce3+ nanophosphors show an intense yellow emission with CIE coordinates (0.47, 0.50) with average correlated color temperature value 3284 was within the range of vertical day light. The present study successfully demonstrates solution combustion synthesis of nanophosphors for display applications.

In this work, various nano-sized samples of Y 2 O 3, Y 2 O 3 :Eu and Y 2 O 3 :Eu , Sr were prepared by urea solution combustion method. Then the resultant nanopowders were investigated by means of X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR) and photo-luminescence emission spectra. Furthermore, the CIE color coordinate of samples were calculated from photoluminescence emission spectra. Results showed that by doping of strontium, the photoluminescence intensity and chromaticity of Y 2 O 3: Eu phosphor was enhanced while crystallite size was decreased.
