In this work, the structural characteristic and photoluminescence properties of Eu3+^{3 + } doped B2_{2}O3_{3}-TeO2_{2} -ZnO-Na2_{2}O glasses were investigated. These glasses were prepared by a melting method in air, combined with thermal annealing at ... see more

The excitation, emission spectra and and lifetime of Eu-doped borotellurite glasses (BTe) have been investigated. The sideband phonon energy and electron-phonon coupling strength (g) have been found. The intensity parameters O? were calculated from the em... see more

In this work, the structural characteristic and photoluminescence properties were investigated in Eu3+^{3 + } ions-doped B2_{2}O3_{3}-TeO2_{2} --ZnO-Na2_{2}O glasses. These glasses were prepared by the melting method in air, after that thermal annealed... see more

Tin Oxide and Indium doped Tin Oxide (SnO2:In) thin films were deposited on glass and Silicon substrates by  thermal evaporation technique. X-ray diffraction pattern of  pure SnO2 and SnO2:In thin films annealed at 650oC and the results showed t... see more

In this research , we study the effect of substrate temperature (423K and 473K) on structural and optical properties for thin films of cadmium sulfide (CdS) by evaporation thermal deposition method on glass substrates and the thickness was about (390nm).X... see more

The electronic and optical properties of a-Al2O3 after induced by 3-keV Ar+ sputtering  have been studied quantitatively by use of reflection electron energy loss spectroscopy (REELS) spectra. The band gap values of a-Al2O3 was determined from the on... see more

The complex research for the changes in the properties of the printing plates’ printing and gap elements influenced by the printing process short runs was conducted, that allowed to determine the change of printing and gap elements’ surface microgeometry,... see more
