Pure and Magnesium (Mg) doped CuO nanoparticles were effectively prepared by solid state method using Copper Chloride (CuCl2 · 2H2O), Magnesium Chloride (MgCl2 · 6H2O) and Sodium Hydroxide (NaOH). The ITO/TiO2/CuO–M/Cu heterojunctions solutions were fabricated by Dr Blade method at a low reaction temperature of 400 °C. In this analysis the prepared nanostructure were exposed to structural, morphological and optical analysis. The X-ray diffraction peaks results divulged that the prepared nanoparticles are monoclinic structure of CuO which was evidenced from the JCPDS card No. 801916. Morphological analysis result exposed that pure CuO particles exclusively consist of agglomerated irregular spherical shape. The result of the elemental analysis confirmed the presence of Mg2+ in the doped samples. Fourier Transform Infra-Red Spectroscopy results reveals the structural modifications due to the presence of magnesium. Optical absorption measurement spectra demonstrates that band gap shift is due the proportion of Mg.

AbstractNovel luminescent materials Ca3-xSi2O7: xPr3+ were successfully prepared by the high-temperature solid-state method. The crystal structure, morphology, and optical spectrum were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectroscopy, respectively. The XRD patterns of the samples indicate that the crystal structure is monoclinic symmetry. The SEM shows that the selected sample has good crystallinity although its appearance is irregular and scalelike. The peak of the excitation spectrum of the sample is located at around 449 nm, corresponding to 3H4→3P2 transition of Pr3+. The peak of the emission spectrum of the sample is situated at around 612 nm which is attributed to 3P0→3H6 transition of Pr3+, and the colour is orange-red. The optimum concentration for Pr3+ replaced Ca2+ sites in Ca3Si2O7: Pr3+ is 0.75 mol%. The lifetime (8.48 μs) of a typical sample (Ca2.9925Pr0.0075)Si2O7 is obtained. It reveals that orange-red phosphors Ca3-xSi2O7: xPr3+ possess remarkable optical properties and can be used in white light emitting devices.
