Thermal and optical properties of TeO2–ZnO–BaO glasses

Effect of doping of Nd3+ ions in BaO–TeO2–B2O3 glasses: A vibrational and optical study

“…Tellurite glasses doped with rare earth ions have large variety of industrial applications like in the development of optical fibers and lasers covering all the main telecommunication bands, non-linear optical devices, up-conversion lasers and in optical fiber amplifiers [12]. Also, the addition of alkaline earth oxide, like BaO, improves the thermal stability of the glass matrix [13]. Trivalent rare earth ions incorporated glasses show important technological applications in many fields like optical communications, optoelectronic devices, lasers and sensors, color display devices, optical detectors, optical switches, data storage, optical amplifiers, and planar waveguides [14].…”

A comprehensive phononics of phonon assisted energy transfer in the Yb3+ aided upconversion luminescence of Tm3+ and Ho3+ in solids

“…The IR results of our base glass therefore, suggest that it contains a large percentage of TeO 3 units in its structure and hence plenty of Te-O À non-bridging oxygens. In the case of a high barium tellurite glass (4 15 mol%), the modifier Ba 2 þ ion is known [17,18] to remain in a state of strong electrostatic interaction with the nearest Te-O À non-bridging oxygens of the glass because of its large ionic size. Since Ba 2 þ and La 3 þ have similar ionic sizes and La 3 þ like Ba 2 þ acts as a modifier cation in a tellurite glass, La 3 þ ion in this glass should also experience strong electrostatic interaction [19,20] with the nearest Te-O À non-bridging oxygens.…”

Toward an ideal nanomaterial for on-chip Raman laser

“…Although tellurite [35][36][37][38][39][40][41][42] and chalcogenide [43][44][45] -based glasses combine large scattering intensity and bandwidth, giving very high Raman gains, up to 40 times larger than SiO 2 , their fabrication demands particular wise precautions, including controlled melting atmosphere. Thus, silicon dioxide-based glasses, due to their compatibility with the existing optical¯bers technology, are more attractive than tellurite-like materials.…”
