The Relationship between Structural and Optical Properties of GeO2-PbO Glasses
The structural and optical characterization of bulk GeO2-PbO glasses was the goal of this study. In this regard, six different (100-x)GeO2-xPbO (15<x<45) glasses were prepared by conventional melt quenching technique between two steel sheets. The produced samples were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and UV-Vis s...
متن کاملOptical properties of Nd doped Bi2O3-PbO-Ga2O3 glasses.
The optical properties of a new family of neodymium doped BPG (Bi2O3-PbO-Ga2O3 ) glasses are presented. We measured a high refractive index, of 2.5, and a transmission cutoff in the far infrared at 8microm. Three intense emission bands are observed centered at 877nm, 1066nm and 1341nm. The emission cross-section is 10 -20 cm 2 and the total spectral linewidth is 30nm at 1066nm. The Judd-Ofelt p...
متن کاملSpectroscopic properties of the 1.4 μm emission of Tm ions in TeO2-WO3-PbO glasses
In this work, we report the spectroscopic properties of the infrared H4→F4 emission of Tm ions in two different compositions of glasses based on TeO2, WO3, and PbO for three Tm2O3 concentrations (0.1, 0.5, and 1 wt%). Judd-Ofelt intensity parameters have been determined and used to calculate the radiative transition probabilities and radiative lifetimes. The infrared emission at around 1490 nm ...

PbOを 含有す る混合 アル カ リの光学 ガ ラスのNa+_??_K+イ オ ン交換 に 及 ぼす ガラス組成 の影 響 をEPMA,光 学顕微鏡 によ り研究 した. Al2O3/Na2O比 が1.0以 下 では, この比 の増大 に とも ないイオ ン交換の速 度が増大す ることが一般 に知 られて いるが, 本研究 のPbOを 多 く含 むガラス の場合には このAl2O3/Na2O比 の効果が ほ とん ど な い ことが わか った. これ はPb2+イ オ ンが Na+_??_K+イ オ ン交換の際にK+イ オ ンの移動 を抑 え るためであろ う. しか しPbOをAl2O3で 入れ換 えてAl2O3/Na2O比 を増 大 させ る とみかけの拡散 係数 は5倍 増大 し, Al2O3/Na2Oの 比の影 響 がみ られた. した が ってPbOを 多 く含 有す ...
متن کاملDispersion and Nonlinearity in Ultra-Optical Ga2O3 and TiO2-Bi2O3-PbO Glass Systems
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...
