Ratiometric optical thermometer with high-sensitive temperature sensing based on synergetic luminescence of Ce3+-Eu2+ in LiSr4(BO3)3 phosphors

Abstract Single-phase Ce3+, Eu2+ co-doped LiSr4(BO3)3 phosphors are successfully prepared via solid reaction process. The crystal structure, luminescence characteristics and thermal quenching performance of LiSr4(BO3)3:Ce3+, Eu2+ samples are systematically studied. The presence of two crystallographic positions of Sr2+ ions in LiSr4(BO3)3 host makes the emission bands of Ce3+ ion and Eu2+ ion exhibit asymmetry. Based on the configuration coordinate model, the thermal quenching of luminescence from Ce3+ ion and Eu2+ ion is investigated in detail. The temperature-sensitive performance is further studied by analyzing the temperature-dependent luminescence spectra of LiSr4(BO3)3:0.06Ce3+, 0.04Eu2+ phosphor. The maximum absolute and relative sensitivities are 0.057 K-1 and 4.017% K−1, respectively, which are better than many previously reported inorganic optical thermometry materials. Besides, the emissions of Ce3+ ion and Eu2+ ion are clearly separated, providing good signal discrimination ability. The results demonstrate that LiSr4(BO3)3:Ce3+, Eu2+ phosphors have outstanding temperature-sensitive properties and can be the excellent optical thermometric materials.

Up-conversion luminescence properties and energy transfer mechanism of SrAl2B2O7: Er3+@Yb3+ phosphors

Abstract The Er3+@Yb3+ co-doped SrAl2B2O7 phosphors were prepared by a sol-gel auto-combustion method. The components, microstructure and up-conversion (UC) properties of samples were investigated systematically. The phosphors emitted red light and green light under the excitation of 980 nm wavelength. The intensity of red emission and green emission nearly linearly decreased with increasing ambient temperatures. The red emission, green emission and their intensity ratio as a function of Er3+ concentrations and Yb3+ concentrations were studied in detail. The results show that 4.0% Er3+ and 8.0% Yb3+ doped samples can obtain the best luminescence intensity while the best light purity cannot be obtained simultaneously. The intensity of red and green emission was measured as a function of excitation power. It indicates that there was no photon avalanche mechanism for SrAl2B2O7: Er3+@Yb3+ due to the absence of sharp change of n values. The UC luminescence corresponded to a two-photon absorption process which was illustrated by the energy transfer mechanism and the steady-state rate equations. Because of the controllable monochromatic luminescence and excellent temperature-dependent luminescence properties, the SrAl2B2O7: Er3+@Yb3+ phosphors have potential application in the fields of non-contact temperature measurement and bio-polychromatic label.

Triarylboron/Triarylamine-Functionalized 2,2'-Bipyridine Ligands and Their Copper(I) Complexes.

We report herein three new either -BMes2 (Mes = mesityl) or -NPh2 group-functionalized 2,2'-bipyridine ligands-4,4'-(p-BMes2-phenyl-C≡C)2-2,2'-bpy (BB-bpy), 4-(p-BMes2-phenyl-C≡C)-4'-(p-NPh2-phenyl-C≡C)-2,2'-bpy (BN-bpy), and 4,4'-(p- NPh2-phenyl-C≡C)2-2,2'-bpy (NN-bpy)-along with their heteroleptic copper(I) complexes Cu(L)(PPh3)2(BF4) (L = BB-bpy, BN-bpy, and NN-bpy, respectively). The electron-donor and -acceptor units are connected to the bipyridine core via acetylene linkers. The incorporation of acetylene linkers decreases the dihedral angle between the bridging phenyl and pyridine rings, resulting in a nearly coplanar geometry of the ligands. All free ligands display temperature-dependent luminescence changes, which may be explained by the twisted intramolecular charge-transfer mechanism. Binding with Cu(I) results in significantly red-shifted emission maxima for the heteroleptic complexes Cu(NNbpy)(PPh3)2(BF4) [Cu(NNbpy)] and Cu(BNbpy)(PPh3)2(BF4) [Cu(BNbpy)] relative to those of the free ligands. The electronic and photophysical properties of all compounds were investigated by electrochemical, absorption, and emission spectroscopic analyses as well as density functional theory calculations.

Crystal structure and admirable luminescence properties of novel red emitting BiOCl: Eu3+ phosphors for indoor illumination

The BiOCl: Eu3+ phosphors were synthesized, utilizing a solid-state reaction method. The crystal structure and morphology of the Eu3+-doped BiOCl were elucidated. The Eu3+-activated BiOCl phosphors showed broad adsorption in the near-ultraviolet region, which emitted intense red emission with the color purity of 71.8%. The quantum yield of the Bi0.95OCl: 0.05Eu3+ phosphor was found to be 0.323. Moreover, the recorded temperature-dependent luminescence spectra indicate that the emission intensity at 150 °C could still remain 80% of that at room temperature, which also verified an excellent thermal resistance performance for the Bi0.95OCl: 0.05Eu3+ sample, which have great potential for indoor illumination.

Temperature dependent near-infrared emission and energy transfer of NaY(MoO4)2:Re (Re = Er3+/Nd3+, Tm3+) crystals

To investigate the energy transfer between Er3+ and Nd3+, Tm3+ ions, NaY(MoO4)2:Re (Re = Er3+/Nd3+, Tm3+) crystals were grown by the Vertical Bridgman method using spontaneous crystallization. The temperature-dependent luminescence properties of the crystals between 298 and 473 K under 980 nm excitation were investigated. The emission intensities decreased with the increasing temperature due to the thermal quenching effect. Compared to Er3+ doped NaY(MoO4)2, the emission intensity at 1534 nm reduced significantly. The crystals gave intense and characteristic emission of Tm3+ and Nd3+ in near-infrared emission region due to sensitization by Er3+ ions. The fluorescence lifetimes (4I13/2→ 4I15/2) of Er3+ single-doped crystals decreased with the addition of Tm3+ and Nd3+ ions. Efficient energy transfer from Er3+ to Tm3+ and Nd3+ ions were observed and the cross relaxation energy transfer efficiency between Er3+ and Nd3+,Tm3+ ions were 77.4% and 51.1%, respectively.

Highly Efficient Deep Blue Luminescence of 2-Coordinate Coinage Metal Complexes Bearing Bulky NHC Benzimidazolyl Carbene.

The structural, photophysical and electrochemical properties of three luminescent 2-coordinate coinage metal (i.e., M = Cu, Ag, Au) complexes bearing a sterically bulky benzimidazolyl carbene, 1,3-bis(2,6-diisopropylphenyl)-1-H-benzo[d]imidazol-2-ylidene (BZI), and carbazolide (Cz) as the anionic ligand were investigated. All the complexes emit in the deep blue region (~430 nm) with relatively narrow spectra (full width at half maximum = 44 nm, 2,300 cm−1) characterized by vibronic fine structure in nonpolar media (methylcyclohexane at room temperature), and with high photoluminescence quantum yields (ΦPL > 80%) and radiative rate constants (kr ~ 7.8 × 105 s−1). The luminescence is solvatochromic, undergoing a red-shift in a polar solvent (CH2Cl2) at room temperature that are accompanied by a decrease in quantum yields (ΦPL < 23%) and radiative rate constants (kr < 4.0 × 104 s−1), whereas the non-radiative rate constants remain nearly constant (knr ~ 1.0 × 105 s−1). The radiative rate is controlled via thermally assisted delayed fluorescence (TADF) and temperature-dependent luminescence studies of the gold complex (AuBZI) in methylcyclohexane solution reveal an energy difference between the lowest singlet and triplet excited states of 920 cm−1. An organic light-emitting diode (OLED) fabricated using AuBZI as a luminescent dopant has an external quantum efficiency of 12% and narrow, deep-blue emission (CIE = 0.16, 0.06).

Photoluminescence and ratiometric optical thermometry in Mn4+/Eu3+ dual-doped phosphor via site-favorable occupation

Optical temperature sensing has been concerned owing to its unique advantages. At present, most researchers construct optical thermometers using optical materials based on thermally coupled levels (TCLs) of rare earth ions. However, it cannot satisfy high temperature sensitivity and good signal discriminability at the same time. Hence, a new temperature sensing strategy based on dual activators is proposed in order to solve the above questions. One of the biggest challenges of this strategy currently faced is the two activators sometimes cannot be excited simultaneously and emit light. Herein, we have designed Mn4+/Eu3+ co-doped double-perovskite type NaLaMgWO6 (NLMW) phosphors via site-favorable occupation principle and investigated their applications in optical temperature sensing. The study showed that Mn4+ and Eu3+ will prefer occupy different cation sites when they enter to the host. Investigating the temperature-dependent luminescence properties of NLMW:Mu4+,Eu3+ phosphor in the range of 303 K–523 K found that both Eu3+ and Mn4+ can emit red emissions but the fluorescence intensity of Mn4+ is much higher than that of Eu3+. And due to Mn4+ and Eu3+ ions have different thermal response where the luminescence intensity of Mn4+ ion decreased more quickly than that of Eu3+ as the temperature increasing, the Mn4+ ion is suitable as temperature signal and Eu3+ ion can be used as reference signal and the fluorescence intensity ratios (FIR) of Mn4+ to Eu3+ were significantly influenced by temperature. Meanwhile, we calculated the thermal quench activation energy of Eu3+ and Mn4+ according to the relationship between intensity and temperature, which are 1.83 eV and 0.367 eV, respectively. Based on the FIR, we further analysed the temperature sensitivity and found that the maximum relative and absolute sensitivity were as high as 0.86% K−1 (523 K) and 3.02% K−1 (363 K), respectively, which is higher than most optical materials based on TCLs. All results indicate that the obtained phosphor could be used to construct self-referencing optical thermometry based on double luminescent centers.

Intense blue emission of perovskite-type fluoride phosphor Cs4Mg3CaF12: Eu2+ as a promising pc-WLEDs material

Abstract An intriguing novel perovskite-type Cs4Mg3CaF12: Eu2+ phosphor with desirable properties for potential application in the field of white light-emitting diodes was first time synthesized. The Rietveld structural refinement, scanning electron microscopy and high resolution transmission electron microscopy were used to determine the crystallographic parameters, morphology and microstructure of Cs4Mg3CaF12: Eu2+ phosphor. The first principle calculation based on the density functional theory further provided a theoretical understanding of the band structure for the undoped Cs4Mg3CaF12 and indicated that it has a large direct band gap of 7.1 eV. Upon the excitation of Cs4Mg3CaF12: Eu2+ phosphor in the broad range of 250–450 nm, the bright blue light emission was observed with the maximum at 474 nm and a full width at half-maximum of 2808 cm−1 that was attributed to the electric-dipole allowed 4f65 d1→4f7 transition of Eu2+ ions. Based on the Dexter’s theory, the concentration quenching mechanism among Eu2+ in the Cs4Mg3CaF12: Eu2+ phosphor was validated to be the dipole-dipole interaction, and the critical distance was determined to be 23.34 A. On the basis of temperature-dependent luminescence measurement, an analysis of the origins of thermal quenching behavior was presented. The Cs4Mg3CaF12: Eu2+ phosphor not only has favorable thermal stability with emission intensity reduction by 20% at T = 473 K in reference to the room temperature level, but also shows the integrated PL intensity 95% as high as that of BaMgAl10O17: Eu2+, internal quantum efficiency of 64% and color purity of 85%. The results of this work indicate that the blue-emitting Cs4Mg3CaF12: Eu2+ phosphor with promising luminescence properties has a capacity for incorporation as a component to the near-UV based phosphor-converted WLEDs.

Cyclic (Amino)(aryl)carbenes Enter the Field of Chromophore Ligands: Expanded π System Leads to Unusually Deep Red Emitting CuI Compounds.

A series of copper(I) complexes bearing a cyclic (amino)(aryl)carbene (CAArC) ligand with various complex geometries have been investigated in great detail with regard to their structural, electronic, and photophysical properties. Comparison of [CuX(CAArC)] (X = Br (1), Cbz (2), acac (3), Ph2acac (4), Cp (5), and Cp* (6)) with known CuI complexes bearing cyclic (amino)(alkyl), monoamido, or diamido carbenes (CAAC, MAC, or DAC, respectively) as chromophore ligands reveals that the expanded π-system of the CAArC leads to relatively low energy absorption maxima between 350 and 550 nm in THF with high absorption coefficients of 5-15 × 103 M-1 cm-1 for 1-6. Furthermore, 1-5 show intense deep red to near-IR emission involving their triplet excited states in the solid state and in PMMA films with λemmax = 621-784 nm. Linear [Cu(Cbz)(DippCAArC)] (2) has been found to be an exceptional deep red (λmax = 621 nm, ϕ = 0.32, τav = 366 ns) thermally activated delayed fluorescence (TADF) emitter with a radiative rate constant kr of ca. 9 × 105 s-1, exceeding those of commercially employed IrIII- or PtII-based emitters. Time-resolved transient absorption and fluorescence upconversion experiments complemented by quantum chemical calculations employing Kohn-Sham density functional theory and multireference configuration interaction methods as well as temperature-dependent steady-state and time-resolved luminescence studies provide a detailed picture of the excited-state dynamics of 2. To demonstrate the potential applicability of this new class of low-energy emitters in future photonic applications, such as nonclassical light sources for quantum communication or quantum cryptography, we have successfully conducted single-molecule photon-correlation experiments of 2, showing distinct antibunching as required for single-photon emitters.

Temperature induced emission enhancement and investigation of Nd3+→Yb3+ energy transfer efficiency in NaGdF4:Nd3+, Yb3+, Er3+ upconverting nanoparticles

Inorganic upconverting nanoparticles that can be excited with 808 nm laser radiation are gaining much attention recently. Living tissues, as well as water do not heat up as intensively when embedded upconverting nanoparticles are excited under such wavelength if compared to commonly used 980 nm laser radiation for excitation. To this end, a series of NaGd0.995-xYbxNd0.005F4 nanoparticles were synthesized in order to investigate energy transfer efficiency between Nd3+ and Yb3+ dopants under 808 nm laser excitation to better suit biological applications. The impact of Yb3+ concentration increase on crystal phase formation as well as downconversion (DC) properties was investigated. Temperature dependent luminescence measurements in NIR region revealed that no thermal quenching of Nd3+−Yb3+ pair in NaGdF4 system was observed in the entire 77–500 K temperature range. Finally, Er3+ ions were introduced in the investigated system in order to obtain multiple excitation and visualisation tool with performance in both VIS and NIR regions. The effective energy difference (ΔE) was also calculated from the thermally coupled levels (TCLs) of Er3+. The promising results and observations of synthesized compounds will be discussed, as NaGd0.475Yb0.5Er0.02Nd0.005F4 has a potential to be used as a luminescent temperature sensor.

Electron-phonon interaction in colloidal CdSe quantum dots embedded in different solid matrices

Colloidal semiconductor nanocrystals (quantum dots, QD) manifest specific temperature dependent luminescence. Here we analyse temperature dependences of CdSe QD luminescence spectrum shift for different composites: polymers, glasses, crystals. The analysis was performed in the terms of electron-phonon coupling, that allows to find and compare the parameters of this interaction. The matrix influence on the T-dependence is also discussed.

Optical and mechanical properties of Li2Mg2(MoO4)3 crystal grown by Czochralski method

A Li2Mg2(MoO4)3 crystal was grown by self-flux Czochralski method in a platinum crucible. The polycrystalline compound was synthesised using standard solid-state reaction method. The purity of the synthesised compound was analysed through powder X-ray diffraction method. Single crystal growth was carried out using a Czochralski chamber in argon atmosphere and the pulling rate was maintained 0.5 mm/h with a rotation rate of 8−10 rpm. The temperature dependent luminescence and decay time measurements were carried out in a temperature range of 10–300 K. The grown crystal sample exhibits an intrinsic emission band in a wavelength range from 320 to 800 nm with the maximum peak at 590 nm. At low temperatures, a significant increase in emission intensity is observed as well as the red shift in the peak position. The luminescence decay time was fitted with three decay components. Thermally stimulated luminescence glow curve was recorded to study the trap centers and found a trap center at 25 K with 3 meV trap depth. Mechanical behaviour of the grown crystal was analysed by using Vicker’s micro hardness testing. The results suggest that Li2Mg2(MoO4)3 crystal can be used for luminescence applications.

Temperature-dependent upconversion luminescence in ferroelectric 1.5%Pr/3%Yb:0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3 transparent ceramics for non-contact thermometry and optical heating

Non-contact optical thermometry based upon fluorescence intensity ratio (FIR) has attracted much attention because of its excellent accuracy and sensitivity. Recently we reported the upconversion luminescence in Pr3+/Yb3+ co-doped 0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3 transparent ceramics [Z. Lv et al., Ceramics International 45 (2019) 10924–10929]. In this article we study the temperature dependence of upconversion emissions from the 1.5%Pr/3%Yb:0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3 transparent ceramics. The FIR between the 1D2-3H4 and 3P0–3H4 emissions fits a thermally coupled-levels-like equation, and exhibits the maximum relative sensitivity of 1.03% K−1 at the temperature 320 K. Meanwhile, the FIRs of IRed/IGreen, IRed/IBlue and IRed/IBG show linear responses versus temperature and illustrate the high constant sensitivities of 1.09%–2.9% K−1, but in a narrow temperature range of 140–240 K. The multiple temperature-sensing performances offer us chances to select distinct response functions on the basis of the practical demands. In addition, laser induced heating was observed in the transparent ceramics. The generated temperature in the ceramics can be accurately monitored and regulated from 329 to 377 K by changing the excitation power from 1.58 to 8.61 W/cm2. The high heating efficiency of ~6.83 K cm2/W makes the transparent ceramics suitable for optical heater. The transparent ceramics exhibit excellent piezoelectric and ferroelectric performances, and thus they are promising candidates for multifunctional optical-electro devices besides non-contact thermometer and optical heater.

Effect of Branching on the Delayed Fluorescence and Phosphorescence of Simple Borylated Arylamines.

A donor-π-acceptor strategy is being well exploited in several fields in view of their robust optical properties. However, the impact of branching in quadrupolar [A-(π-D)2] and octupolar [A-(π-D)3] molecules in comparison to parent dipolar (A-π-D) molecules on the delayed fluorescence and phosphorescence properties is seldom explored. We have presented herein the distinct and contrasting optical properties of a tridurylborane core bearing -NH2 (1-3) and -NMe2 (4-6) donor moieties, wherein the number of donors is increased systematically. Because of propeller molecular architecture, the donor and acceptor are weakly coupled, and the frontier molecular orbitals are spatially localized. All of the compounds show delayed fluorescence under ambient conditions and persistent phosphorescence at low temperature. Solvent-dependent studies and temperature-dependent luminescence measurements established that quadrupolar (2 and 5) and octupolar (3 and 6) compounds underwent symmetry breaking in the excited state. Curiously, delayed fluorescence and phosphorescence spectra are found to be blue-shifted and follow the same trend as the fluorescence upon an increase in the branches. The highest quantum yield was observed for dipolar compounds. Besides, the phosphorescence lifetime decreases with an increase in the number of branches. These interesting experimental observations are further supported by quantum-mechanical calculations.

Solid state white light sources based on a near-UV LED chip are gaining more and more attention. This is due to the increasing efficiency of near-UV-emitting LED chips and wider phosphors selection if compared to devices based on blue LED chips. Here, a brief overview is given of the concepts of generating white light employing near-UV LED and some optical properties of the available phosphors are discussed. Finally, the synthesis and optical properties of very efficient red-emitting Ba2Y5B5O17:Eu3+ phosphor powder and ceramics is reported and discussed in terms of possible application as a red component in near-UV LED-based white light sources.

Temperature-dependent luminescence spectroscopic and mass spectrometric investigations of U(VI) complexation with aqueous silicates in the acidic pH-range

In this study the complexation of U(VI) with orthosilicic acid (H4SiO4) was investigated between pH 3.5 and 5 by combining electrospray ionization mass spectrometry (ESI-MS) and laser-induced luminescence spectroscopy. The ESI-MS experiments performed at a total silicon concentration of 5 · 10−3M (exceeding the solubility of amorphous silica at both pH-values) revealed the formation of oligomeric sodium-silicates in addition to the UO2OSi(OH)3+ species. For the luminescence spectroscopic experiments (25 °C), the U(VI) concentration was fixed at 5 · 10−6M, the silicon concentration was varied between 1.3 · 10−4–1.3 · 10−3M (reducing the formation of silicon oligomers) and the ionic strength was kept constant at 0.2 M NaClO4. The results confirmed the formation of the aqueous UO2OSi(OH)3+ complex. The conditional complexation constant at 25 °C, log *β = −(0.31 ± 0.24), was extrapolated to infinite dilution using the Davies equation, which led to log *β0 = −(0.06 ± 0.24). Further experiments at different temperatures (1–25 °C) allowed the calculation of the molal enthalpy of reaction ΔrHm0 = 45.8 ± 22.5 kJ·mol−1 and molal entropy of reaction ΔrSm0 = 152.5 ± 78.8 J·K−1·mol−1 using the integrated van’t Hoff equation, corroborating an endothermic and entropy driven complexation process.

Bi3+-based luminescent thermometry in perovskite-type CaZrO3 phosphor

Based on the luminescence of Bi3+, novel temperature sensing materials CaZrO3:Bi3+ and CaZrO3:Bi3+/Sm3+ were successfully synthesized by solid-state reaction. The XRD patterns show that the synthesized materials have a pure phase of CaZrO3. The XPS results show that the Bi3+ and Sm3+ can be detected in CaZrO3:Bi3+/Sm3+. With the excitation of 318 nm, the CaZrO3:Bi3+ material shows intense temperature-dependent luminescence. The maximum relative sensitivity can be obtained at 440 K (1.78% K−1). Under the excitation of 408 nm, the CaZrO3:Sm3+ material shows the characteristic emission peaks of Sm3+. The spectral overlap between the emission spectrum of Bi3+ and the excitation spectrum of Sm3+ leads to an energy transfer from Bi3+ to Sm3+ in CaZrO3:Bi3+/Sm3+ phosphor. With the excitation of 318 nm, the emission spectrum of CaZrO3:Bi3+/Sm3+ material shows the characteristic peaks of Bi3+ and Sm3+. The fluorescence decay curves also show the evidence of the energy transfer from Bi3+ to Sm3+. The luminescence intensity ratio of Sm3+ and Bi3+ in CaZrO3:Bi3+/Sm3+ shows obvious temperature dependence. Based on the luminescence intensity ratio, a large relative sensitivity is obtained at 443 K (1.15% K−1).

Dual Emission in a Ligand and Metal Co-Doped Lanthanide-Organic Framework: Color Tuning and Temperature Dependent Luminescence.

In this study, we report the luminescence color tuning in the lanthanide metal-organic framework (LnMOF) ([La(bpdc)Cl(DMF)] (1); bpdc2− = [1,1′-biphenyl]-4,4′-dicarboxylate, DMF = N,N-dimethylformamide) by introducing dual emission properties in a La3+ MOF scaffold through doping with the blue fluorescent 2,2′-diamino-[1,1′-biphenyl]-4,4′-dicarboxylate (dabpdc2−) and the red emissive Eu3+. With a careful adjustment of the relative doping levels of the lanthanide ions and bridging ligands, the color of the luminescence was modulated, while at the same time the photophysical characteristics of the two chromophores were retained. In addition, the photophysical properties of the parent MOF (1) and its doped counterparts with various dabpdc2−/bpdc2− and Eu3+/La3+ ratios and the photoinduced energy transfer pathways that are possible within these materials are discussed. Finally, the temperature dependence study on the emission profile of a doped analogue containing 10% dabpdc2− and 2.5% Eu3+ (7) is presented, highlighting the potential of this family of materials to behave as temperature sensors.

Development of WO3-Gd2O3˗ B2O3 high density glasses doped with Dy3+ for photonics and scintillation materials application

The Dy3+ ions doped tungsten gadolinium borate (Dy-WGdB) glasses were synthesis by the melt-quenching technique with various Dy2O3 concentrations. The physics, optical and several types of luminescence properties in the Dy-WGdB glass samples were researched. Glass densities (~6.0 g/cm3) indicates that the compaction of glass is high and rise with an increment of Dy2O3 concentrations. The Dy-WGdB glass samples absorb photons in visible light (VIS) and near-infrared (NIR) region from the absorption spectra. For photo-, radio- and proton luminescence, the highest emission was observed at 575 nm, corresponding to Dy3+ transition 4F9/2 → 6H13/2. The maximum concentration of Dy2O3 doped in the WGdB glass is 1.0 mol%, which has achieved the highest emission intensity in all three types of luminescence. For 1.0 mol% doped glass, the decay times under pulse X-ray excitation was measured and found to be 0.216 ms. The temperature dependent luminescence spectra of the 1.0% doped glass in a temperature range, 10 K–300 K was measured and found the thermal quenching. In this research, under the photo, X-ray and proton excitation, the WGdB glass doped with Dy2O3 displays the strong luminescence in the VIS region. It has the potential for applications in high-energy and nuclear physics, radiation control and homeland security.
