Crystallization kinetics of the tungsten–tellurite glasses

Characterization of B2O3 and/or WO3 containing tellurite glasses

“…These advantageous properties make tellurite glasses preferable host materials for some infrared and infrared to visible upconversion applications in optical data storage, lasers, sensors and spectroscopic devices [1][2][3][4][5][6].…”

“…Therefore, glass forming agents such as alkalis, heavy metal oxides or halogens are used to obtain tellurite glasses [1][2][3][4][5][6]. It is known that the structure and properties of oxide glasses are strongly dependent on the nature and concentration of the constituent oxides.…”

Investigation on thermal and microstructural characterization of the TeO2–WO3 system

“…Tellurite glasses have been investigated extensively due to their favorable physical and chemical properties such as, relatively lowphonon energy, high refractive index, high dielectric constant, good infrared transmissivity, low glass transition and melting temperature, thermal and chemical stability and high devitrification resistance [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Owing to these numerous properties, tellurite glasses have become preferable host materials for some infrared and infrared to visible upconversion applications in optical data storage, lasers, sensors and spectroscopic devices [5][6][7][8]11,[14][15][16][17][18][19][20].…”

TeO 2 is the main but a conditional glass former; therefore, the addition of a secondary component such as heavy metal oxides, alkalis or halogens increases the glass forming ability [5][6][7][8]. The addition of WO 3 to tellurite glasses provides advantageous properties such as, doping in a wide range, modifying the composition by a third, fourth, and even fifth component, controlling the optical properties, enhancing the chemical stability and devitrification resistance of the glass [1,2,5].…”

In comparison to other tellurite glasses, tungsten-tellurite glasses have slightly higher phonon energy and higher glass transition temperature, therefore they can be used at high optical intensities without exposure to thermal damage [7,8,16,21].…”
