Evolution of poling-assisted bleaching of metal-doped nanocomposite glass with poling conditions
Poling-assisted bleaching was studied with respect to poling time, voltage, and temperature in glass samples having a gradient of silver nanoparticles across the depth. The optical extinction band due to the particles’ surface plasmon resonance around 415 nm was measured and the Maxwell– Garnett effective medium theory was used to fit extinction spectra. Fitting allowed us to determine the evol...
متن کاملPoling-assisted bleaching of metal-doped nanocomposite glass
Thermal poling of soda-lime glass which was doped with spherical or ellipsoidal silver nanoparticles has revealed what we believe to be a phenomenon of general interest in the physics of nanocomposite materials: The field-assisted dissolution of metal nanoparticles embedded in glass. Macroscopically, this phenomenon manifested itself as poling-assisted bleaching of the glass in the sense that t...
متن کاملPeriodic poling of magnesium-oxide-doped lithium niobate
In this article, poling characteristics and periodic poling of magnesium-oxide-doped lithium niobate ~MgLN! are described. Periodic poling was done by the electric field method, with which uniform gratings were produced. The domain wall velocity as a function of poling field was measured and used to determine conditions for self-terminating periodic poling. A computational model for the self-te...
متن کاملThermal poling of glass modified by femtosecond laser irradiation
Thermal poling of silica glass modified by femtosecond laser irradiation is demonstrated. Increase of second-harmonic generation in the irradiated regions is observed. This enhancement is interpreted in terms of structural modifications in silica glass that make the poling process more efficient. Evidence of a change in the distribution of the electrostatic field frozen in glass during poling i...
متن کاملSurface Reactivity Control of a Borosilicate Glass Using Thermal Poling
The ability to control glass surface reactivity at different length enables key properties required for future “smart substrates”. Employing a thermal poling process on a specific borosilicate glass composition can yield a surface with tailored physical and chemical properties. This work shows that during poling, alkali contained in the glass matrix migrates from the anode to the cathode side o...
