EPITAXIAL GROWTH OF CE-DOPED (PB,GD)3(AL,GA)5O12 FILMS AND THEIR OPTICAL AND SCINTILLATION PROPERTIES

Се-doped (Pb,Gd)3(Al,Ga)5O12 single crystalline garnet films were grown using liquid-phase epitaxy from four series of supercooled PbOeB2O3-based melt solutions on Gd3Ga5O12 and Gd3Al2.26Ga2.74O12 single crystal substrates. This study reports the optical and scintillation properties of (Pb,Gd)3(Al,G[r]

Viscous aqueous solutions of chitosan and polyvinyl alcohol (PVA) were blended to enhance miscibility and avoid polymer phase separation. The mixtures were drop-casted and air dried to yield composite film materials that were characterized by equilibrium water uptake, physical stability in aqueous s[r]

These steps ensure that the tip is probing the selected sampling area. Next, the laser is aligned onto the cantilever by ob[r]

In this paper, the optical properties of Dy3 ions in alumino telluroborate glasses have studied using Judd-Ofelt (JO) theory [11, 12] and the CIE 1931 chromaticity diagram. The results have shown that alumino borotellurite glasses doped with Dy3 ions are promising for optical applications and white[r]

As all the samples in this study were grown on transparent sapphire substrates, optical transmission spectroscopy is one of the most convenient yet powerful techniques to study ZnO:Co. Here, our interest was in two wavelen[r]

2.1.2 Multiformity of TCOs
The first realization of a TCO material (CdO, Badeker 1907)) occurred slightly more than a century ago when a thin film of sputter deposited cadmium (Cd) metal underwent incomplete thermal oxidation upon postdeposition heating in air. Later, CdO t[r]

Abstract We report on the molecular beam epitaxy growth of Au-assisted GaAs p-type-doped NW arrays on the n-type GaAs(111)B substrate and their photovoltaic properties. The samples are grown at different substrate temperature within the range from 520 to 580[r]
