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 کاملLatent Prosody Model-Assisted Mandarin Accent Identification
A two-stage latent prosody model-language model (LPM-LM)-based approach is proposed to identify two Mandarin accent types spoken by native speakers in Mainland China and Taiwan. The frontend LPM tokenizes and jointly models the affections of speaker, tone and prosody state of an utterance. The backend LM takes the decoded prosody state sequences and builds n-grams to model the prosodic differen...
متن کاملCalligraphic poling of Lithium Niobate.
We demonstrate a novel technique for instituting complex and arbitrary shaped micron-scale domain patterns in LiNbO3 at room temperature. Fabrication of continuous domains as narrow as 2 microm across and hexagonal patterns of the same order accompanied by real time visualization of the poling process are presented.
متن کاملOrdered nano-scale domains in lithium niobate single crystals via phase-mask assisted all-optical poling
We report the formation of directionally-ordered nanoscale surface domains on the +z face of undoped congruent lithium niobate single crystals by using UV illumination through a phase mask of sub-micron periodicity with an energy fluence between ~90 mJ/cm 2 and 150 mJ/cm 2 at λ=266 nm. We clearly show here that the UV-induced surface ferroelectric domains only nucleate at and propagate along ma...
