Er+ 3doped lead-bismuth tellurite glasses with the composition (75-x) TeO2 − 15 PbO – 10 Bi2O3 - xEr2O3 where (x = 0, 0.5, 1, 1.5, 2 and 2.5 mole%) were synthesized by using melt quenching technique. The influence of Er3+ doping was evaluated through physical and optical properties. The non-crystalline nature of the samples was analyzed by XRD. The density of the samples was increased from 6.387 to 6.528 g.cm− 3. The absorption spectra show eight transition bands corresponding to the transitions from 4I15/2 to 4I13/2, 4I11/2, 4I9/2, 4F9/2, 4S3/2, 4H11/2, 4F7/2 and 4F5/2, respectively. The experimental and calculated oscillator strengths were calculated based on the Judd-Ofelt theory. The intensity parameters follow the trend Ω2 > Ω6 > Ω4. Three emission bands were observed from the fluorescence spectra. The green transition 4S3/2 →4I15/2 is the strongest among other transitions. The color coordinates were determined by using CIE 1931 chromaticity diagram. The highest quantum efficiency was 95.11% for the transition 4S3/2 →4I15/2. The results suggest that the TPBE2 glass is a great promising candidate for photonic applications and fabrication of laser optical devices.

“…Thulium (Tm), a rare earth element, has emerged as a promising dopant for glasses, thanks to its characteristic luminescence properties, which make it suitable for a variety of laser and amplifier applications [6,7]. Among known glass former role, tellurite-based glasses have emerged as a promising glass system for rare earth doping, due to their high refractive index, low phonon energy, and excellent thermal and mechanical properties [8,9,10,11].…”

Tm2O3 doped tellurite-zinc-bismuth-sodium (TZBN) glass samples with varying compositions were prepared through melt quenching technique. The composition of these glass was 60 TeO2 - (30-x) ZnO - 5 Bi2O3 - 5 Na2O - x Tm2O3 with (x = 0.5; 1.0; 1.5; 2.0 and 2.5 mol%). We reported the result of a systematic study of the thermal properties of these glass by using differential thermal analysis (DTA). The thermal characteristics of these glass (glass transition, Tg, crystallization, Tc, and melting, Tm) increased significantly with Tm2O3 content and the glasses were more thermally stable (greater ΔT=Tc-Tg). The glass transition value slightly increased from 314 to 323 °C otherwise thermal stability ΔT changed from 112 to 131°C. The ratio of Tg/Tm values for TZBN doped Thulium glasses were about 0.558 to 0.589, indicated that these glasses possess good thermal stability. The Hruby parameter (Kg) with Tm3+ doped in this study improved glass-forming ability, which is desirable for various applications such as optical fibers drawing and sensors.

“…It has high refractive index, good thermal stability, good chemical and physical durability, low melting points, and low phonon energy [8,9]. However, tellurite can't stand alone as a glass former, because it possesses a high rate of crystallization [10,11]. This problem can be resolved by incorporating metalloid compounds into the glass network.…”

Five boro-tellurite glasses with chemical formula 55TeO2-(12-x)B2O3-32ZnO-(1+x)Na2O (TZBN), (x= 0; 1; 2; 3; 4; mole%) were successfully synthesized by conventional melt-quenching technique. The physical properties of the glass was studied to understand effect of partial substitution between B2O3 and Na2O. The density was measured using pycnometer based on Archimedes law. The other physical properties can be obtained by assisted some mathematical equation. Refer to the measurement, the density was found decreased by 4.905 to 4.590 gr/cm3 because the molecular weight difference between B2O3 and Na2O. Meanwhile the molar volume increased by 25.05 to 27.11 cm3/mole due to higher atomic radii of Na rather than B which raise NBO inside the glass network. Meanwhile, OPD, Vo, polaron radius, inter-ionic distance, packing density,and number of bond per unit volume consequently have been decreased. While the Field strength has increase due to stronger Na-O bonds. Reflects from the results the TZBN glasses could be used as active material for laser.
