TELLURITE GLASSES THESIS

Zainal, Optical properties of ternary tellurite glasses, Materials Science-Poland. Consequently, the refractive index of the substrate changes, which, in turn, modifies the reflectivity of the substrate. The Eg of the three samples were obtained as 3. Luminescence of erbium doped tellurite glass containing silver nanoparticles. Zn1-xMnxO thin films are prepared using 2-methoxyethanol solution of zinc acetate dehydrate and manganese acetate tetrahydrate. The photons of the gas excite electrons from the valence band to the acceptor level, which alters the electron density in these two states.

Transmission and reflection spectrum of the LiNbO3 samples on the infrared-visible-ultraviolet light have been measured. The Eg of the three samples were obtained as 3. All the grown films were polycrystalline with the plane as the preferred orientation and the peak position shifted towards higher diffraction angle with the increase of doping content in the films. Optical Properties of Erbium Doped Tellurite Universiti Teknologi Malaysia Institutional Repository. This change in reflectivity represents the optical signal of the sensor, which is probed remotely with a laser such as a helium-neon laser. Consequently, the refractive index of the substrate changes, which, in turn, modifies the reflectivity of the substrate.

The observed glass density ranges from 5. The dependence of the refractive indices, absorption edge and optical teplurite in congruent HfO2-doped LiNbO3 crystal are reported. Although the midwave infrared mm band is studied in this paper, the approach is applicable to other spectral bands.

The structural properties measured by using FTIR show that as the AgCl content increases, the sharp infrared IR absorption peaks were consistently shifted from The thermal, structural, and optical properties of these glasses were determined and analyzed.
