TL, EPR and optical absorption in natural grossular crystal
(ELSEVIER SCIENCE BV, 2008)
Grossular is one of six members of silicate Garnet group. Two samples GI and GII have been investigated concerning their luminescence thermally stimulated (TL). EPR and optical absorption and the measurements were carried ...
Disorder effects produced by the Mn and H incorporations on the optical absorption edge of Ga1-xMnxAs:H nanocrystalline films
(Elsevier B.V., 2008-12-15)
The optical absorption edges of nanocrystalline Ga1-xMnxAs:H films (0.000 <= x <= 0.081) prepared by sputtering were analyzed. The influence of Mn and hydrogen incorporations were both investigated. The energy dispersive ...
Optical characterization of Argentinean lakes, from deep Andean lakes to shallow Pampean ones
(E Schweizerbartsche Verlags, 2014-06-07)
The purpose of this article is to aboard phytoplankton community as an optically active particulate component of water systems. Mayor concepts of hydrologic optics such as water components and processes that determine the ...
Optical absorption, absorption saturation and a useful figure of merit for chromium doped glasses
(Pergamon-elsevier Science LtdOxfordInglaterra, 1997)
Local electronic structure, optical bandgap and photoluminescence (PL) properties of Ba(Zr0.75Ti0.25)O3 powders
(2013-06-01)
Ba(Zr0.75Ti0.25)O3 (BZT-75/25) powders were synthesized by the polymeric precursor method. Samples were structurally characterized by X-ray diffraction (XRD), Rietveld refinement, X-ray absorption near-edge structure (XANES) ...
Dynamics of energy transfer and frequency upconversion in Tm3+ doped fluoroindate glass
(2004-09-01)
The spectroscopic properties of Tm3+-doped fluoroindate glasses (FIG) were described by single wavelength pumping in the red region. The Judd-Ofelt (J-O) theory was used to obtain the quantum efficiency of the 4f-4f ...
EPR, optical absorption and luminescence studies of Cr3+-doped antimony phosphate glasses
(Elsevier BVAmsterdam, 2014-12)
Antimony phosphate glasses (SbPO) doped with 3 and 6 mol% of Cr3+ were studied by Electron Paramagnetic Resonance (EPR), UV-VIS optical absorption and luminescence spectroscopy. The EPR spectra of Cr3+-doped glasses showed ...
