“…The tellurite based glasses possess high refractive index, better thermal stability as well as chemical durability as compared to fluoride and chalcogenide glasses. They have high RE ions solubility and lower melting temperature as compared to borate, phosphate and silicate glasses [17][18][19][20][21][22][23][24][25]. Table 1 shows the comparison of tellurite based glasses to other glasses in terms of phonon energy, refractive index and melting temperature.…”

The spectroscopic investigations on the Er/Yb ions doped/codoped TeO-ZnO (TZ), TeO-ZnO-WO (TZW) and TeO-ZnO-WO-TiO (TZWTi) heavy metal oxide (HMO) glasses have been made. The absorption, photoluminescence, decay curve and Judd-Ofelt analysis have been performed to optimise the optical properties of the Er/Yb ions. The effect of incorporation of HMOs like WO and TiO in the Er/Yb doped/codoped TZ glass on its optical properties have been investigated. The enhancement in upconversion emission intensity has been explained on the basis of efficient energy transfer and inhomogeneous local field generation around the rare earth ions. The spectroscopic quality factor, absorption and stimulated emission cross-sections, optical gain, quantum efficiency (∼17.53%), energy transfer efficiency (∼61.64%), colour purity (∼94.7%) and ionic nature of the bonding have been determined. The Er-Yb-TZWTi glass can be used in visible lasers, yellowish green optical devices and home appliances.

“…At the same time, immense sci entific and technological advances in the preparation of high purity fluorides of Group I-IV elements and fluoride glasses initiated studies concerned with the application of these materials in other areas, such as laser engineering (fiber lasers and amplifiers, planar waveguides from rare earth doped fluoride glasses), scintillators, and IR optical components, including passive optical fibers [10]. Despite the large number of glass forming fluoride systems, considerable research effort is concentrated on the ZBLAN glasses (system formed by zirconium, barium, lanthanum, aluminum, and sodium fluorides).…”

A series of fluorochlorozirconate glasses doped with manganese ions is synthesized and investigated as possible red‐emitting phosphors in comparison with conventional green‐emitting fluorozirconate glasses doped with Mn2+. It is found that the replacement of fluorine by chlorine ions results in broadening and a long‐wavelength shift of the manganese luminescence band into the red region (peaked at 615 nm) although the emission spectrum still has some contribution of the green sub‐band. It turns out also that decay kinetics of luminescence from fluorochlorozirconate glasses becomes nonexponential in contrast to single‐exponential decay observed for green luminescence from Mn2+‐doped fluorozirconate glasses. The observation of two emission components in the luminescence spectrum of fluorochlorozirconate glasses is interpreted as being due to the presence of two Mn2+ emission centers in different local environments. The presence of 2+ valence states of manganese ions in both types of glasses is confirmed by recording X‐ray absorption near edge structure (XANES) spectra at Mn L2,3 edge. Substitution of F− by Cl− ions in anion sites neighboring to Mn2+, leads to a significant rearrangement of the local environment of Mn2+ ions, which results in the long‐wavelength shift of Mn2+ emission spectrum.
