ABSTRACTThe crystallinity, electrical, and optical properties of the ferroelectric/fluorescent oxide structures using sol-gel-derived (Ba0.6Sr0.4)TiO3 (BST) and (Sr0.8Eu0.2)Bi2.2Ta2O9 (Eu-SBT) grown on STO(110) single crystal substrates were introduced for the first time. In the present structures, the SBT films partly included a (116)-oriented Eu-SBT crystallite. The polarization vs. voltage characteristics of the BST/Eu-SBT structures showed the hysteresis loop caused by spontaneous polarization reversal, and then several emission peaks from Eu3+ ion were observed in a photoluminescence spectrum of a present BST/Eu-SBT structure.

This work proposes the synthesis of nanocrystalline calcium oxide (CaO) pure and doped with different concentrations of lithium (Li[Formula: see text]) ions by sol–gel process. Calcium nitrate (Ca(NO[Formula: see text]4H2O; 99.99%) and lithium nitrate (LiNO3; 99.99%) were used as precursors. The synthesized powders were characterized by several techniques such as: UV-Vis transmission spectroscopy, Fourier Transform Infra-red spectroscopy (FT-IR) and X-ray diffraction (XRD). The main objective of this paper is to study the influence of lithium (Li[Formula: see text] ratio) on the structural and optical properties of synthesized powders. The band gap values decreased with the increasing of Li[Formula: see text] ions in CaO lattice; the slight change in the band gap was directly related to the energy transfer between the CaO excited states and the 2s levels of Li[Formula: see text] ions. The influence of Li[Formula: see text] doping on the physical properties of CaO nanocrystalline will be studied for the first time in this work; no literature has previously published this kind of impurities.
