“…Ohishi et al determined from the phonon sideband spectra associated with 5 D 2 → 7 F 0 transition of Eu 3+ that the highest (maximum) phonon energy for Eu 3+ ‐doped 5MgO‐14.25K 2 O‐14.25Nb 2 O 5 ‐66.5TeO 2 glass is ħω = 726 cm −1 . Hayakawa et al reported the value of ħω = 670 cm −1 for 4ZnO‐20Nb 2 O 5 ‐76TeO 2 glass. Considering the weak compositional dependence of electronic polarizability and glass transition temperature in binary and ternary tellurite glasses (Tables and Figures and ), the highest phonon energy in multi‐component tellurite glasses consisting of basic modifiers and TeO 2 is expected to have a weak compositional dependence, that is, around 700 cm −1 .…”

Tellurite glasses showing unique properties such as low phonon energy and high linear and nonlinear optical properties have been considered as promising materials for photonic device applications. The present article reviews the current status of the electronic polarizability in binary and ternary tellurite glasses and approaches their unique properties. Tellurite glasses consisting of basic modifier oxides (eg, Na2O, ZnO) and basic conditional glass forming oxide (TeO2) exhibit the features of high electronic polarizability and weak chemical bond strength, that is, refractive index‐based large oxide ion polarizability αO2‐(no), large optical basicity ∧(no), small interionic interaction parameter A(no), and small single bond strength BM‐O. The values of αO2‐(no), ∧(no), and A(no) in several tellurite glasses containing WO3, Nb2O5, and Bi2O3 were estimated in this article, and a good correlation was confirmed between ∧(no) and A(no). Unique properties of low glass transition temperature, fragile structural relaxation behavior, poor mechanical properties, high third‐order nonlinear optical susceptibilities in tellurite glasses were discussed from the point of electronic polarizability.

“…From Fig. 9, all of the absorption peaks are f-f transition of Er 3+ ions reported by Carnall's conversion as 4 I 15/ edges around 300 nm are transparent in all visible regions except intrinsic absorption lines due to Er 3+ ions dopant [21]. However, the absorption edge at around 400 nm corresponded to nonlinear absorption via a two photon process which is an important mechanism of down-converting energy process.…”

“…Rare-earth (RE) ion-doped tellurite glasses have attractive optical properties, including high refractive index (>2.0), wide optical window from near-ultraviolet (NUV) to infrared (IR) region and a variety of photoluminescence (PL), as well as low melting point, good chemical stability and high solubility of RE ions. [1][2][3][4][5][6][7][8] Low phonon energy of tellurite glasses (~700 cm -1 ) is beneficial for obtaining high PL intensity of RE ions doped in a tellurite matrix. However, the residual hydroxyl group (-OH) in the glasses can somewhat influence the optical properties and limit transmission in a longer-wavelength region, because OH groups strongly absorb IR light at ~ 3,000 cm -1 .…”

This paper describes Nd 3+ -ions doped multicomponent tellurite glasses TeO2-TiO2-ZnO (TTZ) applicable to advanced optical devices, which were characterized by UV-Vis-NIR absorption, Raman, and photoluminescence (PL) techniques. Not only did we perform experimental characterizations but also theoretically predicted the PL properties of Nd 3+ -doped TTZ glasses by using the Judd-Ofelt theory. The influence of the residual hydroxyl (OH) groups and types of crucible used in the melt preparation on the structures and optical properties of TTZ glasses was investigated. We found that the use of a Pt crucible increased the network-connecting structures of trigonal bipyramidal TeO4 compared to the case of a Al2O3 crucible. Moreover, reducing the OH groups in TTZ glasses improved the optical properties of Nd 3+ -doped TTZ glass, and a higher spectral figure of merit of 8.71 × 10 −24 s cm 2 for Nd 3+ : 4 F3/2→ 4 I11/2 emission at 1,075 nm could be achieved, indicating that Nd 3+doped TTZ glass with lower hydroxyl content is promising for laser or active optical applications.
