Dispersion, as the characteristic variation of refractive index with wavelength, is more pronounced, where the wavelength is approaching to the absorption band. In ultra-optical glasses, the nonlinear refractive index, concerning to the light intensity dependent phenomenon, becomes considerable. Here, two ultra-optical property glass systems; TiO2-Bi2O3-PbO (TBP...

silicon thin layers are deposited on glass substrates with the thickness of 103 nm, 147 nm and 197 nm. the layers are produced with electron gun evaporation method under ultra-high vacuum condition. the optical reectance and the transmittance of produced layers were measured by using spectrophotometer. the optical functions such as, real and imaginary part of refractive index, real and imaginar...

Nowadays, oxyfluoride glasses have received much attention from photonic researchers as they benefit from the advantages of both oxide and fluoride glasses (low phonon energy in parallel with high mechanical and chemical durability). The purppose of this paper was to study the different glass compositions in SiO2-Al2O3-K2O-BaF2 system and i...

Mn(II) doped P2O5-ZnO-CaO glasses are being characterized by techniques like XRD, UVVisible and different physical properties. XRD patterns in present glasses have confirmed the amorphous nature of glass samples. The optical absorption spectrum exhibited three bands which are characteristic of Mn(II) in distorted octahedral site symmetry., The density is one of the tools to reveal the degree of...

This paper proposes a measuring apparatus and method for simultaneous determination of the thermal expansion coefficient biaxial Young’s modulus indium tin oxide (ITO) thin films. ITO films simultaneously coated on N-BK7 S-TIM35 glass substrates were prepared by direct current (DC) magnetron sputtering deposition. The thermo-mechanical parameters investigated experimentally. Thermal stress in s...
