SiO(2) in density functional theory and beyond
(WILEY-BLACKWELL, 2011)
We present the first-principle electronic structure calculation on an amorphous material including many-body corrections within the GW approximation. We show that the inclusion of the local field effects in the ...
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 ...

Optical, vibrational and fluorescence recombination pathway properties of nano SiO2-PVA composite films
(Elsevier, 2019)
We report optical and spectroscopic investigations on polyvinyl alcohol (PVA)/silica composite free standing films. Amorphous silica nanoparticles are synthesized from rice husk ash using pyrolysis technique. PVA/silica ...
Rhodamine B-containing silica films from TEOS precursor: Substrate surface effects detected by photoluminescence
(Elsevier B.V., 2007-02-15)
This work presents the study of substrate surface effects on rhodamine B-containing silica films obtained from TEOS (tetraethylorthosilicate) acid hydrolysis. Soda-lime glass substrates were treated with basic solution ...

SnO2 nanoparticles functionalized in amorphous silica and glass
(Elsevier B.V. Sa, 2009-10-25)
Two different routes to obtain SnO2 nanoparticles, undoped and doped with rare earth metals (Eu or Pr), are described herein. The first route was based on the polymeric precursor method that led to the obtainment of SnO2 ...
