Devitrification Behavior of Sol-Gel Derived ZrO2-SiO2 Rare-Earth Doped Glasses: Correlation between Structural and Optical Properties

Yb-Sensitized Rare-Earth Doped Optical Glasses

The temperature e ect upon infrared-to-visible frequency upconversion uorescence emission in o -resonance infrared excited Yb-sensitized rare-earth doped optical glasses is theoretically and experimentally investigated. We have examined samples of Er3+/Yb-codoped Ga2S3:La2O3 chalcogenide glasses and germanosilicate optical bers, and Ga2O3:La2O3 chalcogenide and uoroindate glasses codoped with P...

Sol-Gel Fabrication of Rare-Earth Doped Photonic Components

The use of sol-gel to fabricate silica-on-silicon waveguides, and particularly erbium-doped waveguide amplifiers, is reviewed. In particular, efforts to use sol-gel to improve molecular homogeneity in heavily Er-doped silica-based films is discussed. A variety of material studies carried out to investigate the gain limitations found in these materials is then presented. These include x-ray diff...

Mechanical properties of sol–gel derived SiO2 nanotubes

The mechanical properties of thick-walled SiO2 nanotubes (NTs) prepared by a sol-gel method while using Ag nanowires (NWs) as templates were measured by using different methods. In situ scanning electron microscopy (SEM) cantilever beam bending tests were carried out by using a nanomanipulator equipped with a force sensor in order to investigate plasticity and flexural response of NTs. Nanoinde...

Growth and Optical Properties Investigation of Pure and Al-doped SnO2 Nanostructures by Sol-Gel Method

SnO2 nanoparticles with different percentage of Al (5%, 15%, and25%) were synthesized by sol-gel method. The structure and nature of nanoparticles are determined by of X-ray diffraction analysis. Also, morphology of the samples is evaluated by SEM. Moreover, the optical properties of the samples are investigated with UV-Visible and FT-IR. The XRD patterns are in...
