Rare Earth Elements-doped glasses have applications in many fields, and for example, Al and Ce codoping in silica optical fibers is usually done to attenuate the optical degradation (photodarkening) of, e.g. Yb and Tm doped silica optical fibers. To shed some light on the effect of codoping on the optical properties and the glass structure of...

LaF3 is commonly added to oxide glass, in particular to silica, to form oxyfluoride glass. After appropriate thermal treatment at a temperature lower than 800 °C, usually, glass ceramics are obtained. Recently, LaF3 nanoparticles have been used as precursors to obtain amorphous nanoparticles of undefined composition in optical fiber. However,...

Network structures of glasses and glass fibers are tailored by glass designers using various combinations of oxides or raw materials to achieve desirable properties for specific applications. It has been well accepted in the glass community that the glass network structures are affected not only by composition, but also melt history (melting...
Analytical methods for glass characterization. In the glass industry, knowledge of the chemical composition and atomic structural of glasses is important for quality control on production sites or for the research and development of new products. In this chapter, we will briefly describe different methods that can be used to easily obtain...

Lasers and amplifiers based on thulium-doped silica fibers require improved spectroscopic properties. In this context, one of the most promising approaches is based on the embedding of thulium ions in nanoparticles of tailored composition and structure. This paper presents various methods used to produce thulium-doped nanoparticles inside...
