“…As shown in Table II, the parameter Ω 2 of TBTH0.5 is larger than that of other glasses, which indicates a stronger covalent bonding between Ho 3+ ions and their ligand ions. 18,19 The parameter Ω 4 and Ω 6 of TBTH0.5 are smaller than that of sulfide glass, 20 but larger than that of silica, 21 fluoride 18 and tellurite glass, 22 which means that the mechanical properties of TBTH0.5 is better. 19 It is noted that the parameter Ω 4 /Ω 6 of this work is larger than that of other tellurite glass such as TBBL 22 and TWZ 23 glass.…”

A series of Tm3+/Ho3+ co-doped tellurite glasses were successfully prepared by the melt-quenching method. The spectroscopic properties around 2 μm of Tm3+/Ho3+ co-doped tellurite glasses were studied under 808 nm laser excitation. Based on the Judd-Ofelt theory, the phenomenological intensity parameters Ωt (t=2, 4, 6) of the Tm3+/Ho3+ co-doped tellurite glasses were calculated. In addition, the emission cross-section and the gain coefficient of Ho3+ were calculated, and the maximum values are 0.76×10-20 and 1.38 cm-1, respectively. These results portend that the Tm3+/Ho3+ co-doped tellurite glass has excellent spectroscopic properties and attractive laser performance in mid-infrared waveband.

Reacting RE2O3 and H3BO3 in an ultra‐alkaline NaOH hydroflux at about 250 °C yielded pure, crystalline samples of Na2[RE(BO3)(OH)2] (RE = Y, Gd–Er). The compounds dehydrate to Na3RE(BO3)2 upon heating in air to about 500 °C. Na2[RE(BO3)(OH)2] (RE = Tb–Er) are photoluminescent under UV radiation. Their UV‐Vis spectra show the typical absorptions associated with 4f‐4f transitions and absorption edges in the UV (band gaps ≥ 5.7 eV). The RE3+ cation is coordinated by seven oxygen atoms, which define a distorted pentagonal bipyramid. The bipyramids share trans‐edges of their base forming infinite chains. Triangular (BO3)3– groups connect the chains into layers. The crystal structure of Na2[Ho(BO3)(OH)2] was investigated at various temperatures in the range 100 K ≤ T ≤ 320 K. Above 310(2) K, the compound crystallizes in the orthorhombic space group Cmcm (β‐phase), below, it undergoes a displacive phase transition of second order resulting in a monoclinic structure in space group C2/c (α‐phase). The critical exponents derived from different structural parameters indicate a cooperative distortion of the borate layers, but a rather uncorrelated adaptation of the sodium cations to their local environment. The other compounds of the series also adopt the structure of the α‐phase at 296 K.
