The optical absorption edge of nanocrystalline Ga(1-x)Mn(x)N films deposited by reactive sputtering
(Iop Publishing Ltd, 2008-02-06)
We have focused on the optical absorption edge of nanocrystalline Ga(1-x)Mn(x)N (0.00 <= x <= 0.18) films deposited by reactive RF magnetron sputtering. The films obtained are nanocrystalline with grain sizes of about 25 ...
UV optical absorption spectra analysis of beryl crystals from Brazil
(ELSEVIER SCIENCE BV, 2010)
The spectral decomposition analysis was applied to the optical absorption spectra of green and colorless beryl crystals from the Brazilian Eastern Pegmatitic province in the natural state, Submitted to heat treatment and ...
Light induced permanent modifications of the nonlinear optical properties of semiconductor doped glasses
(Pergamon-elsevier Science LtdOxfordInglaterra, 1996)
Characterization of the reversible photoinduced optical changes in Sb-based glasses
(Elsevier B.V., 2006-09-15)
Changes occurring in absorption coefficients when glasses in the SbPO4-WO3 binary system were irradiated by light, at the edge of the absorption band, were measured in real time. These glasses present good thermal and ...
Study of the colloidal stability and optical properties of sunscreen creams
(2019-01-01)
Sunscreen formulations containing inorganic/organic filters or mixture of them were synthesized by oil/water dispersion. The viscosity measurements show that sunscreen formulations are time-dependent non-Newtonian fluids. ...
Thermoluminescent and optical absorption properties of neodymium doped yttrium aluminoborate and yttrium calcium borate glasses
(ELSEVIER SCIENCE BVAmsterdam, 2009)
Neodymium doped yttrium aluminoborate and yttrium calcium borate glasses were prepared by the conventional melting-quenching technique with neodymium concentration varying from 0.10 to 1.0 mol%. The obtained glasses present ...
Facile Synthesis of Tellurium Nanowires and Study of Their Third-Order Nonlinear Optical Properties
(Sociedade Brasileira de Química, 2017-01-01)
We report on the synthesis of single-crystalline tellurium nanowires with different aspect-ratios prepared via facile surfactant-assisted synthesis under mild conditions. Short and long Te nanowires were synthesized by the ...
Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...
Optical properties of highly turbid shallow lakes with contrasting turbidity origins: The ecological and water management implications
(Academic Press Ltd-elsevier Science Ltd, 2013-11-30)
A comprehensive optical study of three highly turbid shallow lakes was presented. The lakes contained very high concentrations of optically active substances [OASs] with clear differences in total suspended solid [TSS] ...
MAGNETO-OPTICAL ABSORPTION AND PHOTOMAGNETISM IN EUROPIUM CHALCOGENIDES
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
The absorption threshold in EuTe and EuSe was investigated as a function of applied magnetic field in the Faraday geometry. A well-resolved doublet of sharp dichroic lines was observed when the magnetic field induced ...
