Magnetic characteristics of nanocrystalline GaMnN films deposited by reactive sputtering
(2013-01-29)
The magnetic characteristics of Ga1-xMnxN nanocrystalline films (x = 0.08 and x = 0.18), grown by reactive sputtering onto amorphous silica substrates (a-SiO2), are shown. Further than the dominant paramagnetic-like ...

Enhanced optical properties of germanate and tellurite glasses containing metal or semiconductor nanoparticles
(2013-05-13)
Germanium- and tellurium-based glasses have been largely studied due to their recognized potential for photonics. In this paper, we review our recent studies that include the investigation of the Stokes and anti-Stokes ...
Metal-Organic Semiconductor Nanostructures for Surface-Enhanced Raman Scattering
(Soc Applied Spectroscopy, 2011-02-01)
Metal-organic semiconductor films are fabricated as co-evaporated films. It is demonstrated that the technique can be used to fabricate metal-semiconductor surface-enhanced Raman scattering (SERS) or surface-enhanced ...
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 ...
Cooperative frequency upconversion in Yb3+-Tb3+ codoped fluoroindate glass
(1998-12-15)
We report the observation of cooperative frequency upconversion in a fluoroindate glass. The experiments were performed by exciting Yb3+-Tb3+ codoped samples with an infrared diode laser. The process is monitored through ...

Heterogeneous photocatalytic treatment of organic dyes in air and aqueous media
(2008-12-01)
This review focuses on the heterogeneous photocatalytic treatment of organic dyes in air and water. Representative studies spanning approximately three decades are included in this review. These studies have mostly used ...
Effect of the Rashba and Dresselhaus spin-splitting terms on the electron g factor in semiconductor quantum wells under applied magnetic fields
(2008-03-01)
We use the Ogg-McCombe Hamiltonian together with the Dresselhaus and Rashba spin-splitting terms to find the g factor of conduction electrons in GaAs-(Ga,Al)As semiconductor quantum wells (QWS) (either symmetric or asymmetric) ...
