Název v původním jazyce
Pure TeO2 glass: Influence of synthesis conditions on linear and non-linear optical, magneto-optical and structural properties
Popis výsledku v původním jazyce
The first systematic study of linear and non-linear optical, magneto-optical and structural properties of pure TeO(2) glass is presented with regard to different synthesis and material processing conditions. Prepared glasses were synthesized by the intermittent quenching from 900 °C in platinum or alumina crucibles and characterized prior to and after optical polishing. The position of the long-wavelength/phonon absorption edge was investigated using various optical models and experimentally obtained data of refractive index and Verdet constants were used for the estimation of magneto-optical anomaly parameter. During synthesis in alumina crucible, up to about 11 wt.% of Al(2)O(3) incorporates into the glass (verified by EDS/XRF and Raman/FTIR spectroscopy) partially transforming the original pure TeO(2) glass backbone structure composed of [TeO(4)] trigonal bipyramids to [TeO(3+1)] and [TeO(3)] structural units with the expected integration of Al into Te-O-Al bridges. The presence of Al(2)O(3) results in lowered density rho (5.60 -> 4.72 g cm(-3)), refractive index n(1550) (2.086 -> 1.927) and Verdet constant V(632) (36.3 -> 21.9 rad T(-1) m(-1)) and in increased optical-band-gap energy E(g) (3.69 -> 3.72 eV) and Abbe number nu(D) (19.9 -> 26.9) compared to pure TeO(2) glass prepared in platinum crucible. A dataset of the obtained complex optical parameters (refractive index and extinction coefficient) in the wide spectral range of 193 11000 nm is included in the supplementary part.
