“…3 COOH, in molar % were prepared by sol-gel methods based on procedure [19]. The solution of tetraethoxysilane (TEOS) and N,Ndimethylformamide (DMF) in ethanol and water with nitric acid as a catalyst was hydrolyzed for 30 min at room temperature to make sure that all components were totally mixed.…”

“…The solution of tetraethoxysilane (TEOS) and N,Ndimethylformamide (DMF) in ethanol and water with nitric acid as a catalyst was hydrolyzed for 30 min at room temperature to make sure that all components were totally mixed. Subsequently, Pb(CH 3 COO) 2 and Eu(CH 3 COO) 3 were dissolved in water with trifluoroacetic acid and added dropwise into the first solution. Obtained transparent solution was stirred during 5 h at room temperature.…”

“…The trivalent europium ions due to orange/red emission are one of the most important of the rare earth ions and can be applied in solid-state laser, plasma display panel or spectroscopic probe [1][2][3][4][5]. Oxyfluoride glass-ceramics based on the silicate glassy matrix are unique class of materials that combine the advantages of physical and chemical properties of an oxide glass with the high solubility of the rare earth ions.…”

This paper reports an optical investigation of Eu 3? :PbF 2 nanocrystals distributed into silica glasses fabricated by sol-gel methods. The sample microstructure was investigated using scanning transmission electron microscopy. The b-cubic PbF 2 crystalline phase was identified using X-ray diffraction analysis. The observed emission bands correspond to 5 D 0 ? 7 F J (J = 0-4) transitions of Eu 3? . The spectroscopic parameters for Eu 3? ions were determined based on excitation and emission measurements as well as luminescence decay analysis. Emission originating from 5 D 0 state of Eu 3? ions in sample containing PbF 2 nanocrystals is long-lived in comparison to precursor sol-gel silica glasses.

“…Transparent oxyfluoride nano-glass-ceramics (GC), made photo-luminescent by doping with rare-earth ions, have been shown recently to be promising materials for new optical devices such as bulk laser media and amplifying laser fibers for optical communications [1][2][3][4]. These materials are easier to prepare than single crystals and can be made in a wide variety of shapes and sizes; they are also characterized by high chemical and mechanical stabilities as oxides [1][2][3][4].…”

“…These materials are easier to prepare than single crystals and can be made in a wide variety of shapes and sizes; they are also characterized by high chemical and mechanical stabilities as oxides [1][2][3][4]. Oxyfluoride GC can be obtained by the process of the heat treatment of glass close to the glass transition temperature, in which fluoride crystallites are dispersed in the oxide glass matrix [5][6][7][8].…”

Oxyfluoride glasses are the basic materials for obtaining transparent glass-ceramic (TGC) which can be used in a wide range of optoelectronics devices such as: amplifiers, up-conversion, telescopes, laser sources. Oxyfluoride TGC is obtained by the control heat treatment of the parent glass due to low phonon nanocrystalline phases. The oxyfluoride glasses from the sodium-lead-silica system were the object of investigation. The influence of fluoride content on the thermal properties of glasses was analyzed. Thermal characteristics of glasses like the transition temperature T g , the temperature for the crystallization onset T x , and the maximum crystallization temperature T c , thermal stability parameter were determined by DTA/DSC method. The linear expansion coefficients of oxyfluoride glasses as a function of temperature were measured using a thermomechanical analyzer (TMA 7 Perkin-Elmer). The effect of crystallization on the thermal expansion coefficient and softening temperature T s was found.

This review deals with the formation and physical properties of noncrystalline materials in oxide and nonoxide systems. Structural aspects are also developed. Oxide materials are silica‐based glasses, borate, and phosphate glasses, while nonoxide systems include halide and chalcogenide glasses. They are described in terms of chemical compositions and thermal and optical properties. Special attention is paid to the unique properties of nonoxide glasses for infrared‐light transmission and rare earth emissions. Some applications in the fields of infrared optics, infrared fiber sensors, fiber lasers, and amplifiers are shown. In a special section, the formation and properties of metallic glasses are presented, with special focus on chemical, magnetic, and mechanical properties.
