Blue upconversion enhancement by a factor of 200 in Tm 3+-doped tellurite glass by codoping with Nd 3+ ions
(2002-11-15)
We investigated near-infrared-to-blue upconversion from thulium (Tm 3+) doped in tellurite glasses upon continuous wave excitation near 800 nm. We observed an enhancement of over two orders of magnitude of the upconverted ...

Raman Studies of Carbon-Doped GaAs Layers Grown by a Metallic-Arsenic-Based Metalorganic Chemical Vapor Deposition System
(2012-12-17)
High-quality p type GaAs epilayers were grown by metalorganic chemical vapor deposition using trimethylgallium
and metallic arsenic as gallium and arsenic sources, respectively. The range of hole concentration analyzed ...

Effect of lithium doping on the evolution of rheological and structural properties during gelation of siloxane-poly(oxypropylene) nanocomposites
(2005-09-21)
The influence of lithium doping on the evolution of viscoelastic properties and structure during the gelation of siloxane-poly(oxypropylene) (PPO) nanocomposites has been studied. For several [O]/[Li] ratios (O being the ...

Structural characterization of undoped and Sb-doped SnO2 thin films fired at different temperatures
(Blackwell Munksgaard, 2003-06-01)
SnO2 thin films were obtained by the sol-gel method starting from inorganic precursor solutions. In this work, we compare the structure of undoped and Sb-doped SnO2 films prepared by dip-coating. The films were deposited ...
