Tri-doped Tellurite Glass Research Articles

Er3+/Yb3+/Ho3+ tri-doped no-core fiber temperature sensor based on fluorescence intensity ratio technology: towards high stability and accurate measurements.

In this paper, the green upconversion (UC) fluorescence emission from E r 3+/Y b 3+/H o 3+ tri-doped tellurite glass is investigated for temperature sensing. The doping of H o 3+ ions not only enhances the chance of energy level transition but also avoids the influence of the thermal effect caused by the proximity of 2 H 11/2 and 4 S 3/2 energy levels. The luminescence characteristics at different Y b 3+ and H o 3+ ion concentration doping molar ratios were investigated, and the strongest luminescence characteristics were exhibited when the Y b 3+ ion concentration was at 5mol% and H o 3+ at 0.2mol%. Based on this, a tri-doped T e O 2-Z n O-B i 2 O 3 (TZB) no-core fiber was fabricated and connected with multimode fibers (MMFs) to form a temperature sensor. The temperature sensing performance of the tri-doped TZB temperature sensor was evaluated in detail over the temperature range of 255-365K. The repeatability and stability of the temperature sensor was experimentally verified. The E r 3+/Y b 3+/H o 3+ tri-doped sensor can be used for noninvasive optical temperature sensing in the fields of environmental monitoring, biological sensing, and industrial process temperature control, etc.

Tailoring near-infrared luminescence with Er3+/Tm3+/Yb3+ tri-doped tellurite glasses for applications in the C, L and U bands

In this work, co-doped and tri-doped systems with Er3+, Tm3+ and Yb3+ were evaluated in tungsten-tellurite glasses to extend the amplification range of current Erbium-Doped Fiber Amplifiers (EDFAs). The conditions of synthesis showed that the use of appropriate atmosphere was efficient to decrease the OH content and enhance the Er3+ emission. Spectroscopic studies on Er3+ and Tm3+ co-doped glasses revealed an emission from 1500 to 2000 nm with the energy transfer between both ions and the luminescence from Er3+: 4I13/2 → 4I15/2 and Tm3+:3F4 → 4H6. The addition of Yb3+ increased around 4 times in the NIR luminescence at 1535 nm. Lifetime measurements showed an increase of energy transfer efficiency (η) from Er3+ to Tm3+ as Tm2O3 content increased. In addition, temperature-dependent luminescence is studied for co-doped and tri-doped systems in the range of −180 to 75 °C. As temperature decreases, the ratio between Er3+ and Tm3+ emissions increases whereas the introduction of Yb3+ considerably enhanced the emission from Er3+ at 1535 nm related to Tm3+. This study demonstrates that the NIR emission of these tellurite glasses, both in intensity and bandwidth, can be considerably tailored by means of the dopant content, synthesis conditions, and temperature.

Effect of Nb2O5 on the ∼2.0 μm band luminescence of Ho3+/Tm3+/Ce3+ tri-doped tellurite glass

In this work, the effect of Nb2O5 oxide on the ∼2.0 μm band luminescence of Ho3+/Tm3+/Ce3+ tri-doped tellurite glass with composition of TeO2–ZnO–La2O3 was studied. The doped tellurite glass was synthesized by using the melt-quenching method. Under the pumping of 808 nm laser diode (LD), a broad and relatively flat fluorescence emission ranging from 1600 to 2200 nm with a full width at half maximum (FWHM) of 374 nm was obtained by optimizing the concentration combination of Ho3+, Tm3+ and Ce3+ ions. The observed broad luminescence was attributed to the spectral overlapping between the energy level transitions from 3F4 to 3H6 of Tm3+ at 1.82 μm and that from 5I7 to 5I8 of Ho3+ at 2.0 μm. Further, an increment by about 143% in peak intensity of 1600∼2200 nm broad luminescence was found after the introduction of Nb2O5 oxide, which is due to the enhanced energy transfer from Tm3+ to Ho3+ ions, and the increased multi-phonon relaxation (MPR) rate from higher levels to fluorescence emitting levels. It can be inferred from the results that a potential gain medium suitable for applications in optoelectronic devices operating at ∼2.0 μm band can be produced by incorporating an appropriate amount of Nb2O5 oxide into Ho3+/Tm3+/Ce3+ tri-doped tellurite glass.

Luminescence enhanced temperature sensor based on the up-conversion emission in Er3+/Yb3+/Mo6+ tri-doped tellurite fiber

In this study, the green up-conversion (UC) fluorescence emission in Er3+/Yb3+/Mo6+ tri-doped tellurite glasses (TeO2–ZnO–Li2CO3–Bi2O3, TZLB) was explored for temperature sensing. The doping of Mo6+ ions allowed enhanced luminescence at moderate power pumping, avoiding the introduction of undesired laser-induced thermal effects while improving the spectral signal-to-noise ratio. The luminescence characteristics were investigated in detail at different doping molar ratio of Mo6+ ions, and the strongest was observed at 8 mol%. Drawing on tri-doped TZLB glass with the strongest UC emission intensity, a tri-doped TZLB fiber was fabricated and coupled with two multimode fibers (MMFs) via Ultraviolet (UV) adhesive, forming the temperature sensor. The sensor was further encapsulated by a silica tube sealed with Ultraviolet adhesive, overcoming the poor mechanical property of tellurite fiber. The temperature information could be demodulated based on the fluorescence intensity ratio technique. The temperature sensing performance of the tri-doped TZLB sensor was investigated as temperature varied from 258 to 420 K and its repeatability was experimentally verified. The Er3+/Yb3+/Mo6+ tri-doped TZLB has an application prospect in the field of lighting, and the so-based temperature sensor is expected to be applied to thermal detection in the fields of medical diagnostics, environmental monitoring, and optical thermometers, etc.

A new Nd3+/Tm3+/Ho3+ tri-doped tellurite glass for multifunctional applications

Nd3+, Tm3+ and Ho3+ doped tellurite glasses with good thermal stability were prepared by conventional melt-quenching technique. The near-infrared luminescence properties were investigated under the excitation of 808 nm laser diode (LD). In the studied spectral range of 1200–2200 nm, two ultra-broadband luminescence bands of 1300–1600 nm and 1600–2200 nm were observed simultaneously in Nd3+/Tm3+/Ho3+ tri-doped tellurite glass with amounts of 0.015 mol% Nd2O3, 0.32 mol% Tm2O3 and 0.045 mol% Ho2O3, which have not been reported yet for this tri-doped combination. The full width at half maximum (FWHM) of this two luminescence bands were up to 203 and 374 nm respectively. In addition, the glass transition temperature Tg and the difference ΔT of the prepared tellurite glass were about 379°C and 136°C respectively. The structural property, spectroscopic property and fluorescence decay behavior were investigated to better understand the luminescence phenomena. The result of two ultra-broadband luminescence bands obtained at the same time in present work indicates that Nd3+/Tm3+/Ho3+ tri-doped tellurite glass is a promising multifunctional application material.

Dy3+/Er3+/Tm3+ tri-doped tellurite glass with enhanced broadband mid-infrared emission

Dy3+/Er3+/Tm3+ tri-doped tellurite glass was synthesized using melt-quenching technology, and the enhanced broadband mid-infrared band luminescence around 3.0 µm was reported for the first time under the excitation of 808 nm laser diode. The broadband mid-infrared luminescence observed in the range of 2600–3200 nm comes from the spectral overlapping of Er3+:2.7 µm and Dy3+:2.84 µm emissions, while the significant enhancement is mainly contributed by the energy transfers from Er3+:4I13/2 to Dy3+:6H11/2, Er3+:4I13/2 to Tm3+:3F4 and Tm3+:3F4 to Dy3+:6H11/2 levels. Compared with Dy3+ single-doped tellurite glass, the peak intensity of this mid-infrared band luminescence in tellurite glass tri-doped with 0.5 mol% Dy2O3, 0.5 mol% Er2O3 and 1.0 mol% Tm2O3 increases by about 214%. Additionally, the spectroscopic properties of Dy3+ ions were investigated by applying Judd-Ofelt theory and the energy transfer mechanism was analyzed to understand the enhanced broadband luminescence phenomena. The obtained results reveal that Dy3+/Er3+/Tm3+ tri-doped tellurite glass is a promising lasing medium for 3.0 µm band mid-infrared broadband photonic devices.

Intense 2.85 μm mid-infrared emissions in Yb3+/Ho3+ codoped and Yb3+/Er3+/Ho3+ tridoped TBLL fluorotellurite glasses and their energy transfer mechanism

Yb 3+ /Ho 3+ codoped and Yb 3+ /Er 3+ /Ho 3+ tridoped TeO 2 –BaF 2 –LaF 3 –La 2 O 3 (TBLL) fluorotellurite glasses with low OH − absorption (0.026 cm -1 ), high glass transition temperature (434 °C) and low phonon energy (784 cm -1 ) were prepared. Their mid-infrared fluorescence properties and related energy transfer (ET) mechanism were studied under 980 nm excitation. A strong emission at 2.85 μm was realized in Yb 3+ /Ho 3+ codoped tellurite glass, which was attributed to the high-efficiency ET from Yb 3+ ions to Ho 3+ , and the ET efficiency was 91.1%. Further introduction of Er 3+ ions induced stronger 2.85 μm emission, and the ET efficiency was improved to 96.2%, ascribed to the establishment of more ET channels and Er 3+ ions playing the role of ET bridge between Yb 3+ and Ho 3+ ions. These results indicate that the Yb 3+ /Er 3+ /Ho 3+ tridoped tellurite glass could be a hopeful gain medium material for the ∼3 μm fiber laser.

Pr3+/Tm3+/Er3+ tri-doped tellurite glass with ultra-broadband luminescence in the optical communication band

Pr3+/Tm3+/Er3+ tri-doped tellurite glass was synthesised using a melt-quenching method, and the broadband luminescent properties were measured in the near-infrared band. With an optimal combination of the three ions, a broadband luminescence ranging from 1280 to 1630 nm, located within the optical communication window of silica transmission fibre, was acquired under 808 nm excitation. The broadband luminescence comprises three bands: 1.34 μm (Pr3+), 1.47 μm (Tm3+), and 1.53 μm (Er3+); and the full width at half-maximum was about 248 nm. This valuable result is of great significance for novel broadband fibre amplifiers and ultra-short pulsed lasers.

Ultra-broadband 4.1 μm mid-infrared emission of Ho3+ realized by the introduction of Tm3+ and Ce3+

Ho3+/Tm3+/Ce3+ tri-doped tellurite glasses with lower phonon energy (761 cm−1) were prepared by melt quenching in this paper. Performing XRD, Raman, DSC performance characterization, it was concluded that the synthetic tellurite glass sample had a multi-element structure, and the ΔT of the prepared tellurite glass was 138 °C, which can be used for fiber drawing with good thermal stability. Under the 808 nm LD excitation, an ultra-broadband emission from 3800 to 4200 nm mid-infrared band with full-width at half-maximum (FWHM) of the prepared glass about 309 nm was achieved, which can be applied to mid-infrared ultra-wide tunable all-fiber laser. With the introduction of CeO2, the up-conversion emission were suppressed and strong mid-infrared emission were obtained, at the same time, the fluorescence lifetime of the sample was significantly prolonged, which are mainly due to the cross relaxation between Ho3+ and Ce3+, the energy transfer mechanism was further analyzed through the energy level transition process. The maximum emission cross section and gain coefficient of the tellurite glass were 1.01 × 10−20 cm2 and 1.13 cm−1, which were improved compared with the previously reported tellurite glasses. The results demonstrate that the Ho3+/Tm3+/Ce3+ tri-doped tellurite glass is a promising mid-infrared optical material.

Effective enhancement on mid-infrared fluorescence emission of Ho3+/Yb3+ doped tellurite glass introduced Ag nanoparticles

Abstract In this paper, Ho3+, Yb3+ and metal Ag nanoparticles (NPs) tri-doped tellurite glass were synthesized by melt quenching. Combining X-ray diffraction, Raman spectroscopy, and Differential thermal analysis tests, multiple structural units were found in the synthetic glass samples which provided the possibility to achieve high concentration and uniform doping of rare earth ions without degrading the glass forming ability and thermal stability. The fluorescence emission of glasses at 2 μm, 3.9 μm, and 4.1 μm were focused on, as a consequence, the Ho3+/Yb3+/AgNPs tri-doped tellurite glass achieved strong emission at 2 μm, 3.9 μm and 4.1 μm, and the full width at half maximum (FWHM) at 4.1 μm is 316 nm under the 980 nm LD excitation, which realized broadband fluorescence emission. In addition, the fluorescence lifetimes of the glass at 2 μm, 3.9 μm and 4.1 μm are 4.79 ms, 3.81 ms and 4.28 ms meaning the lower laser oscillation threshold the glass holds. It is particularly noteworthy that the emission intensity had been greatly improved about 30% at 2 μm and 27% at 3.9 μm and 4.1 μm with the introduction of AgCl into the matrix, respectively, which was mainly effected by local surface plasmon resonance (LSPR) of AgNPs and the energy transfer between Ag species and Ho3+, whereas the content of AgCl must be strictly controlled to prevent the concentration quenching to decrease the emission intensity. The obtained results demonstrate that Ho3+/Yb3+/AgNPs tri-doped tellurite glass possesses an ideal application prospect on mid-infrared fiber and laser materials.

Nd3+-Er3+-Pr3+ tri-doped tellurite glasses with lower phonon energy (768 cm−1) were prepared by conventional melt-quenching method. Under the excitation of 488nm, an ultra-broadband emission from 760 to 1150 nm with full-width at half-maximum (FWHM) of about 262 nm was observed in the prepared Nd3+-Er3+-Pr3+ tri-doped glass sample, larger than that of the recently reported glasses. The DSC curve shows that the prepared tellurite glass has high glass transition temperature (Tg=382°C) and good thermal stability (ΔT=203°C). The gain coefficient, maximum absorption and emission cross section of Nd3+-Er3+-Pr3+ tri-doped tellurite glass for Nd3+:4F3/2→4I9/2 and Er3+:4I11/2→4I15/2 transitions are calculated as 0.41 cm−1, 0.80 × 10−20 cm2, 1.07 × 10−20 cm2, 0.35 cm−1, 0.37 × 10−20 cm2 and 0.45 × 10−20 cm2, respectively. Compared with the recently reported glasses, these values were effectively improved. This means that the prepared tellurite glass has better fluorescence emission and laser gain performance.

Abstract Nd3+-Er3+-Pr3+ tri-doped tellurite glasses with lower phonon energy (766 cm−1) were prepared by conventional melt-quenching method. Under the excitation of 488 nm, an ultra-broadband emission from 1250 to 1650 nm with full-width at half-maximum (FWHM) of about 332 nm was found in Nd3+-Er3+-Pr3+ tri-doped tellurite glass, larger than that of recently reported tellurite glasses.

Compared with the recently reported glasses, these values were improved. This indicates that better laser gain and fluorescence emission could be obtained in the prepared tellurite glass. The results showed that Nd3+-Er3+-Pr3+ tri-doped tellurite glass is a promising near-infrared optical material.

Pr3+-, Er3+-, and Nd3+-doped tellurite glasses were synthesized via traditional melting and quenching, and two super-broad near-infrared 800–1100 nm and 1250–1650 nm emission bands were observed simultaneously in the as-prepared Pr3+-Er3+-Nd3+ tri-doped glass sample under a 488 nm xenon lamp. The 800–1100 nm emission band was caused by the spectral overlapping of Pr3+:3P1,0→1G4, Pr3+:1D2→3F4,3, Er3+:4S3/2→4I11/2, Er3+:4I11/2→4I15/2, Nd3+:4F3/2→4I9/2, and Nd3+:4F3/2→4I11/2 radiation transitions, while the 1250–1650 nm emission band was produced by the Nd3+:4F3/2→4I13/2, Pr3+:1G4→3H5, Pr3+:1D2→1G4, Pr3+:3F3→3H4, and Er3+:4I13/2→4I15/2 radiation transitions, and the latter had a full width at half maximum (FWHM) of approximately 296 nm. The results demonstrate that tellurite glass tri-doped with appropriate concentrations of Pr3+, Er3+, and Nd3+ ions can be applied to many fields such as medical imaging, broadband fiber amplifiers, and broadband lighting sources at the same time.

Influence of Yb2O3 on the 1.53 μm spectroscopic properties in Er3+/Ce3+ co-doped TeO2-WO3-Na2O-Nb2O5 glasses

The Yb2O3 component was introduced into the Er3+/Ce3+ co-doped tellurite glasses with the composition of TeO2-WO3-Na2O-Nb2O5 to study the effect of Yb3+ on the 1.53 μm spectroscopic properties of Er3+. The X-ray diffraction (XRD) curve and Raman spectrum were measured to investigate the structure nature of synthesized tellurite glasses. The absorption spectrum, upconversion emission spectrum and fluorescence spectrum were measured to evaluate the improved effect of Yb3+ concentration on the 1.53 μm band fluorescence of Er3+. Results of the measured 1.53 μm band fluorescence intensity show a significant improvement with the increase of Yb3+ concentration, while the total quantum efficiency reveals a similar increasing trend. The results of the present work indicate that Er3+/Ce3+/Yb3+ tri-doped tellurite glass has good prospect as a promising gain medium applied for the 1.53 μm broadband amplifier.

In this paper, Nd3+/Yb3+/Ho3+ tri-doped scheme was developed and the enhanced 2.0 µm band emission of Ho3+ by introducing the third Yb3+ into Nd3+/Ho3+ co-doped tellurite glass was obtained. Under the excitation of 808 nm laser diode (LD), the near-infrared emission spectrum displayed that the 2.0 µm band peak intensity was increased by about 2.4 times when introducing 1 mol% amount of Yb2O3, which is attributed to the newly established energy transfer channel of Nd3+ → Yb3+ → Ho3+. The decrease of Nd3+:4F3/2 level lifetime and increase of Ho3+:5I7 level lifetime evaluated from the fluorescence decay curves demonstrated the observed luminescent phenomenon. The mechanism analysis about energy transfer together with micro-coefficient calculation were carried out to understand the role of Yb3+ as a bridge and phonon assistance in the accomplishment of energy transfers among Nd3+, Yb3+ and Ho3+. Meanwhile, the 2.0 µm band spectroscopic property of Ho3+, the structural information and thermal stability of tellurite glass were investigated by application of Judd-Ofelt theory, and measurements of XRD pattern and DSC curve respectively. The obtained results indicate that Nd3+/Yb3+/Ho3+ tri-doped tellurite glass with good thermal stability is a promising candidate material in improving 2.0 µm band emission performance of Ho3+.

Ultra-broadband 1.0 μm band emission spectroscopy in Pr3+/Nd3+/Yb3+ tri-doped tellurite glass.

Tellurite glasses doped with trivalent Pr3+, Nd3+ and Yb3+ ions were prepared using conventional high-temperature melt-quenching technique and their optical absorption, near-infrared emission, X-ray diffraction (XRD), Raman spectrum, and differential scanning calorimeter (DSC) curve were measured. Upon excitation at 488 nm, an ultra-broadband near-infrared emission extending from 800 to 1120 nm was found to appear owing to the overlapping of the emission bands centered at 900 and 1035 nm of Pr3+, 880 and 1060 nm of Nd3+ as well as 978 nm of Yb3+, respectively. The energy transfer mechanism among Pr3+, Nd3+ and Yb3+ ions which was responsible for the observed ultra-broadband near-infrared emission was investigated to understand the luminescent phenomena. In addition, Judd-Ofelt theory was applied to predict the radiative properties of doped rare-earth ions, and some important radiative parameters such as radiative transition probability, branching ratio and radiative lifetime were derived. Meanwhile, the structural information of amorphous nature and vibrational units was revealed by the XRD pattern and Raman spectrum. Also, the DSC curve displayed the good thermal stability to resist thermal damage for studied tellurite glass with high glass transition temperature. The results indicate that Pr3+/Nd3+/Yb3+ tri-doped tellurite glass is a promising material for ultra-broadband fiber lasers operating around 1.0 μm near-infrared band.

The near-infrared band luminescence from Er3+/Pr3+/Nd3+ tri-doped tellurite glasses were investigated in this work. The tellurite glasses were prepared by melt-quenching method and under the excitation of 488 nm laser, an ultra-broadband emission from 1260 to 1650 nm with FWHM about 256 nm was found to appear owing to the perfect overlapping of emission bands from Er3+, Pr3+ and Nd3+, respectively. Additionally, the studied tellurite glasses possess high glass transition temperature with Tg > 420 °C. The ultra-broadband and flat emission properties as well as good thermal stability indicates that Er3+/Pr3+/Nd3+ tri-doped tellurite glass has great application prospect in near-infrared band broadband fiber amplifiers.

2.0 µm band emission enhancement and energy transfer in Ho3+/Yb3+/Er3+ tri-doped tellurite glasses

Abstract Improving the infrared-band luminescent property of rare-earth doped materials is a challenging task. In this work, the enhanced 2.0 µm band emission study in Ho3+/ Yb3+/Er3+ tri-doped tellurite glasses with composition TeO2-ZnO-WO3-La2O3 was given. The tellurite glasses were prepared by conventional melt-quenching technique and characterized by absorption spectrum, emission spectrum, fluorescence decay curve, differential scanning calorimeter (DSC) curve, X-ray diffraction (XRD) pattern and Raman spectrum. The DSC curve displays the good thermal stability with glass transition temperature larger than 420 °C, the XRD pattern reveals the amorphous state nature and Raman spectrum clarifies the vibrational units of glass network. Based on the absorption spectrum, important spectroscopic parameters like spontaneous radiative transition probability, radiative lifetime, absorption and emission cross-sections, and gain coefficient are determined to predict the potential luminescent properties in near-infrared band, while the fluorescence spectrum demonstrates the enhanced 2.0 µm band emission of Ho3+:5I7 → 5I8 radiative transition aroused by Er3+ introduction. Compared with the Ho3+/Yb3+ co-doped sample, an enhancement of about 93% in 2.0 µm band emission intensity is appeared in the tri-doped tellurite glass after introducing 0.8 mol% amount of Er2O3 under the excitation of 980 nm. The enhanced 2.0 µm band emission is attributed to the energy transfers among Yb3+, Er3+ and Ho3+ ions, and fluorescence decay curves together with the energy transfer mechanism are analyzed to elucidate the observed luminescent enhanced phenomena. The results indicate that Ho3+/Yb3+/Er3+ tri-doped tellurite glass possesses excellent 2.0 µm band luminescent property and can be an attractive candidate for solid-state lasers.

Energy transfer induced 2.0 µm luminescent enhancement in Ho3+/Yb3+/Ce3+ tri-doped tellurite glass

Tellurite glasses doped with Ho3+, Ho3+/Yb3+ and Ho3+/Yb3+/Ce3+ ions have been prepared using conventional melt-quenching method, and characterized respectively by the X-ray diffraction (XRD) pattern, differential scanning calorimeter (DSC) curve, UV–vis–IR absorption spectrum, upconversion spectrum, fluorescence spectrum and fluorescence decay curve to investigate the 2.0 µm band spectroscopic properties of Ho3+, thermal stability and structural nature of glass hosts. Under the excitation of 980 nm laser diode (LD), an intense and broad 2.0 µm band infrared emission originated from the 5I7 → 5I8 transition of Ho3+ was observed in the Ho3+/Yb3+ co-doped tellurite glass and increased further with the addition of Ce3+, which is attributed to the energy transfer (ET) from Yb3+ to Ho3+ as well as the cross-relaxation (CR) between Ho3+ and Ce3+. The quantitative analyses of ET mechanism between the doped rare-earth ions, together with the investigation on the changes of upconversion emission intensity and 2.0 µm fluorescence lifetime with Ce3+ were presented to elucidate the observed 2.0 µm band luminescent enhancement. Meanwhile, important spectroscopic parameters, such as radiative transition probability, absorption and emission cross-sections, and gain coefficient for Ho3+:5I7 → 5I8 transition, were calculated from the measured absorption spectrum to evaluate the potential radiative properties. Additionally, the measured DSC curve reveals the good thermal stability and the XRD pattern confirmed the amorphous structure of prepared glass host.
