Mössbauer spectroscopy was founded more than fifty years ago based on an outstanding discovery by the young German physicist Rudolf Ludwig Mössbauer while working on his Ph.D. thesis. He discovered the recoilless nuclear resonance fluorescence of gamma radiation and was awarded the Nobel Prize in Physics in 1961 as one of the youngest recipients of this most prestigious award. His discovery 15 led to the development of a new technique for measurements of hyperfine interactions between nuclear moments and electromagnetic fields. This method, with highest sharpness of tuning of 10 -13 , yields information on valence state, symmetry, magnetic behavior, phase transition, lattice dynamics and other solid state properties.

“…High-index BaO-SiO 2 -TiO 2 glass showed strong Raman scattering in wide range of wavelengths compared with that of the silica glass. In the BaO-SiO 2 -TiO 2 glass, peaks at 300 and 800 cm −1 originated from bonds of Ti-O and Si-O in the BaO-SiO 2 -TiO 2 glass matrix[19,20]. The intensity of Raman scattering of high-index glass (at 800 cm −1…”

Enhancement of stimulated Raman scattering in terrace-microspheres

et al. 2011

Terrace-microspheres of high-index glass (BaO-SiO 2-TiO 2 glass, n D ¼ 1:93) containing 0:3 ppm of Nd 3þ were used to investigate the interaction between Raman scattering due to a glass matrix and fluorescence due to Nd 3þ. The terrace-microspheres were pumped with a tunable CW Ti:sapphire laser (790 nm-830 nm wavelength) for changing pumping wavelengths. With pumping in the 800-830 nm wavelength region, there was a spectral overlap between Raman scattering and Nd 3þ fluorescence. Under such conditions, Nd 3þ fluorescence works as a seeding and an amplifier of stimulated Raman scattering (SRS), resulting in SRS enhancement. With pumping of 20 mW power at around 830 nm wavelength, the terrace-microspheres showed the strongest SRS gain, 5-6 times of that of 790 nm wavelength pumping. SRS thresholds of the terrace-microspheres were improved from 3 mW (790 nm wavelength pumping) to 0:3 mW (830 nm pumping) due to the enhancement effect. The potential application for a multiwavelength Raman laser with a low threshold was demonstrated in the near-IR region (λ ¼ 840-940 nm).

Glass is accompanying people from the early times of mankind. First it was the natural glass generated by the volcanic processes and the glass "produced" by the impact of meteors on the earth. During formation of the earth, highly siliceous melts of rocks froze to natural glasses such as obsidians. After some time the people start the glass melting. Glass was first produced by man about 4,000 years ago in ancient Egypt. From this time the need of the knowledge of glass composition, structure and properties is dated. These are the typical questions answered by the glass chemistry [1][2][3][4][5][6].The aim of the present contribution is point out the mutual relationships between the understanding of the glass structure and construction of the thermodynamic models of glass. Finally the method of studying glass structure based on combined statistical treatment of Raman spectra with the thermodynamic model will be presented together with the example of its application on the chalcogenide glasses from the pseudobinary system As 2 S 3 -As 2 Se 3 .11.2 Thermodynamics of Glass Formation [7,8] The glass is commonly defined (e.g. [9]) as the non-crystalline solid obtained by cooling the melt without crystallization. Despite the fact that glass can be produced also by other ways, like by the sol-gel method or by the amorphization of crystalline solid [6], it is worth noting the uncommon situation when the method of preparation
