Structural and Spectroscopic properties of Eu3+ doped SiO2–TiO2 nanoparticles for photonic applications

The Eu3+-doped TiO2 nanoparticles in sol gel silicate glasses of composition (80-x)SiO2 + 20TiO2 + 0.5xEu2O3, (SiTiEu) where x = 0.0 0.5, 1.5, 2.5 and 3.5 mol%, have been prepared by sol-gel technique. The glass samples were investigated by thermos-gravimetric analysis (TGA/DTA), ATR-FTIR, XRD, SEM, TEM, EDX, optical absorption and photoluminescence emission spectroscopy at room temperature (RT). The absorption wavelength of TiO2 doped sol-gel silicate glass were red shifted due to a reduction in band gap energy with increasing annealing temperatures. According to the TEM images, all of the particles were spherical and had an average diameter is around 10 nm. The visible spectra of the Eu3+ doped TiO2 nanoparticles in sol-gel silicate glasses displayed characteristic PL emission 5D0→7FJ (J = 0, 1, 2, 3, 4, 5) transitions of Eu3+ ions at 370 nm excitation. The anatase TiO2:1.5Eu3+ nanocomposite showed high photoluminescence emission at 370 nm excitation, which was attributed to the f-f transitions of Eu3+. The hypersensitive 5D0→7F2 transition was responsible for the major red emission. From the recorded spectra, radiative parameters and Judd-Ofelt (JO) intensity parameters were computed. The Eu3+ co-doped TiO2 nanoparticles in sol-gel silicate glasses displayed emissions mostly in the red regions realized from a CIE chromaticity diagram. The results suggested that materials may be used as an optical material of technological importance such as display devices and also for optical amplifier.

Thermo-gravimetric analysis (TGA/DTA) tells that complexes are stable upto 290 °C, and photoluminescence (PL) analysis. By using PL data and luminescence decay time (τ), the transition rates, quantum efficiency and the Judd-Ofelt intensity parameters were determined. The luminescence emission spectra for complexes in both states show an intense emission peak (5D0→7F2) at 614 nm (solid) and at 613 nm (solution) of Eu3+ which is responsible to make them an efficient red color emitter in luminescent devices.

Percentage branching ratio (βr) and CIE color coordinates value of all synthesized complexes in both states were analyzed. The value of Percentage branching ratio (βr) is 79.92–84.65 % in solid state whereas in solution state the value lies in range 49.37–75.37 % and values of percentage branching ratio (βr) suggests that these complexes are used in lasers and radars systems. The color purity [CP(%)] values are found to be 92.96–94.31 % in solid and 81.24–93.70 % in solution. The band gap is calculated and found to be in the range of 3.7–3.9 eV and used in semiconductor and electroluminescent devices. The complexes (C1–C6) are considered as warm light source because the complexes heaving values of correlated color temperature (CCT) in between 2785 and 3024 K in solid state and 1734 to 2912 K in solution state, which can be efficiently used in LEDs present in hotels, lounges and in many home appliances. The above investigation suggests that synthesized complexes are significant emitters with broad area of utility in laser, electroluminescent materials and display devices.

Luminescent characteristics at ∼2.9 μm in Lu3+ modified Dy3+/Tm3+ co-doped LiYF4 single crystal

The single crystals specimens comprising 0.3 mol% Dy3+, 0.5 mol% Tm3+ and γ mol% Lu3+ doped LiYF4 (γ = 0, 0.3, 0.5, and 1.5) were meticulously synthesized using the Bridgman method, with the specific aim of catering to applications in the ∼2.9 μm laser domain. The microstructure of the obtained single crystal was investigated by conducting X-ray diffraction (XRD) measurements. The Judd-Ofelt (J-O) intensity parameters of the Dy3+ ion and the impacts of Lu3+ doping on fluorescence characteristics of the 6H13/2 (Dy3+) level were studied. The Dy3+/Tm3+ doped LiYF4 single crystal exhibits ∼52 % enhancement in emission intensity at ∼2.9 μm (Dy3+: 6H13/2→6H15/2) through a favorable introduction of Lu3+ ions into the single crystal at 808 nm LD excitation. The Tm3+/Dy3+/Lu3+ triply doped single crystal exhibited a maximum emission cross section of 2.480 × 10−20 cm2 at 2904 nm. The fluorescent lifetimes of the Dy3+: 6H13/2 level in the single crystals were determined to be located in the range of 2.78 ms–3.33 ms. The microscopic mechanism of energy transfer (ET) between Tm3+ and Dy3+ ions were investigated and the ET coefficients from 3H4 level of Tm3+ ion to 6F5/2 of Dy3+ ion (ET1) and 3F4 of Tm3+ to 6H11/2 of Dy3+ (ET2) in the triply doped single crystal were calculated, yielding values of 3.422 × 10−39 cm6/s and 5.768 × 10−39 cm6/s, separately. The results clearly demonstrated that the mid-infrared luminescence at ∼2.9 μm from Dy3+ ions can be significantly enhanced by the strategic incorporation of appropriate Lu3+ ions into Tm3+/Dy3+: LiYF4 single crystal.

The impact of heat treatment on the luminescence properties of Dy/Ag co-doped sodium alumina borate glasses

The sodium alumina borate glasses were synthesized by conventional melt-quenching method and heat treated with different durations to ensure the formation and growth of Ag nanoparticles. Transmission electron microscope measurements revealed that the average nanoparticle size increases with the heat treatment duration. The bonding nature between Dy3+ ions and surrounding ligands was getting more covalent with HT. Judd-Ofelt intensity parameters proved the asymmetric nature around Dy3+. The most intense emission and excitation bands of Dy3+ ions were observed for 6 h heat-treated glass (HT-6h). Intense blue (483 nm) and yellow (572 nm) emissions were obtained in which the yellow one has the highest radiative parameters approving the suitability of glasses for yellow laser applications. Based on colorimetric results emission closest to white light can be generated by HT-6h under 426 nm excitation. The decay time of 4F9/2 → 6H13/2 transition increases with heat treatment attributed to the combined effect of the enhanced local electric field induced by the Ag nanoparticles and energy transfer from Ag species to Dy3+ ions. The findings show that Dy3+/Ag+ co-doped sodium alumina borate glasses are potential materials for photonic applications.

Photophysical properties of tris(benzoyltrifluoroacetonate)Eu(III) with pyrazole complex and its precursor

The precursor, [Eu(btfa)3(H2O)2] with yield of 84 % and its complex with monodentate pyrazole, [Eu(btfa)3(pz)2] were isolated successfully. To the best of our knowledge, no previous reports of such synthesis with a high yield of [Eu(btfa)3(H2O)2] exist in literature. Single crystal X-ray diffraction (SC-XRD) analysis demonstrates, octa-coordinate environment of Eu (III) in both the complexes. The geometry of these complexes was obtained from SHAPE v2.1 and found triangular dodecahedron (D2d) and square antiprism (D4d) for [Eu(btfa)3(H2O)2] and [Eu(btfa)3(pz)2], respectively. These complexes were further characterized by elemental, thermal analysis (TGA/DTA) and ATR-IR spectroscopy. The lifetime of [Eu(btfa)3(pz)2] (546 ± 0.35 μs) is much longer than that of its precursor [Eu(btfa)3(H2O)] (335 ± 0.11 μs). The overall quantum yield of [Eu(btfa)3(pz)2] complex (21 %) is seven times larger than its precursor (3 %). The Judd-Ofelt intensity parameters accredit that [Eu(btfa)3(pz)2] is more polarizable (Ω2 = 33.56 × 10-20 cm2) than its precursor, [Eu(btfa)3(H2O)2] (Ω2 = 13.95 × 10-20 cm2).

White light-emitting ZnO:Dy3+ nanophosphors: delving into the spectroscopic parameters via Judd-Ofelt analysis.

Developing a single-phase white emitting nanophosphor with high quantum efficiency has become a hotspot for scientific world. Herein, single-phase white-light emitting Zn1-xO:xDy3+ nanophosphors have been synthesized via a sonochemical method. X-ray diffraction analysis and Raman spectroscopy-based investigations confirmed the hexagonal wurtzite phase for Zn1-xO:xDy3+ nanophosphors with preferential growth along the (101) plane. Scanning electron microscopy images showed the formation of a ribbon-shaped morphology with a diameter of ∼25 nm. The emission spectra of the Dy3+-activated ZnO nanophosphors exhibited three distinct peaks, namely blue (480 nm), yellow (572 nm), and red (635 nm) emissions, under near-UV excitations related to the 4F9/2 → 6HJ (J = 15/2, 13/2, and 11/2) transitions of Dy3+ ions. The values of CIE chromaticity coordinates for the optimized phosphor (x = 0.329, y = 0.334) with correlated color temperature (CCT) of 5657 K indicated cool white-light emission from the phosphor. The thermal stability of ZnO:Dy3+ nanophosphors was probed by temperature-dependent luminescence. Quantitative evaluation of Judd-Ofelt intensity parameters, radiative parameters, luminescence decay, and quantum efficiency of Zn1-xO:xDy3+ using the J-O theory suggests that these nanophosphors are promising luminescent media for commercial white LEDs and other display devices.

The emission wavelength (λem), calculated fluorescence branching ratios (βR), radiative emission probabilities (AR), total radiative emission probability (Ar) and radiative lifetime (τR) of Dy3+ in CaSrF4 crystal are investigated for the transitions from energy levels 4F9/2 (474 nm), 4I15/2 (452 nm), 6P5/2 (364 nm) and 6P7/2 (348 nm) to related sublevels. Dy:CaSrF4 crystal is a promising gain medium for a continuous wave or tunable solid state visible micro-laser under the pump wavelength of 348 nm, 364 nm and 474 nm.

Study of structural, luminescence and Judd-Ofelt calculations for Ce3+ doped ZnS phosphors for display applications

This paper discusses the luminescence properties of novel Zn(1-x)S: xCe3+ (x = 0, 0.01, 0.02, 0.03, 0.1, 0.2 and 0.3) prepared via conventional solid-state reaction method at low temperature. The XRD results revealed that all synthesized phosphors have hexagonal structure. The strain was calculated using size-strain plot (SSP) method. The FTIR study identifies the various vibrational modes present in the synthesized phosphors. The structural and luminescence characteristics of the prepared samples were enhanced by Ce3+ substitution. The optical band gap energies were found to be decreasing with Ce3+ substitution. The optimal Ce3+ content for superior blue emission is found to be x = 10 mol %. The blue emission supports the incorporation of Ce3+ ions within the ZnS lattice, which is again confirmed by Ω2, Judd-Ofelt intensity parameter. The high value of Ω2 indicates the symmetry of site occupies of Ce3+ ions are lower. The obtained critical distance of energy transfer between Ce3+ ions is calculated to be 6.3095 Å, which implies that the exchange interaction mechanism is a multipolar exchange. The high efficiency, branching ratio, stimulated cross section and the optical parameters indicate that the prepared phosphor materials have efficient blue light emission for display applications.

High pressure-driven effects on the structural and spectroscopic attributes of Eu3+-doped amorphous silicates

The present study focuses on synthesizing and investigating the structure of Eu3+-doped sodium calcium silicate and calcium alumino silicate glasses under extreme high-pressure conditions. For a thorough understanding of glassy systems in extreme conditions, we conducted in-situ micro-luminescence experiments using a diamond anvil cell, reaching pressures up to 16 GPa. Hydrostatic pressure demonstrated a notable impact on luminescence, attributed to the nephelauxetic effect causing the contraction of central-ion-ligand distances. The band transitions of Eu3+ from the 5D0 to 7F1,2 states revealed pronounced pressure-induced splitting, highlighting the pressure influence on crystal-field properties. The energy shifts for the 5D0 → 7F1 transitions were determined to be 0.14 nmGPa−1 and 0.20 nmGPa−1 for sodium calcium silicate and calcium alumino silicate, respectively. These distinct slope differences indicated a lower structural adaptability of the former glass, resulting in reduced deformability under high-pressure conditions. Furthermore, as pressure increased, the asymmetry ratio of the 5D0 → 7F2/1 transitions decreased, though it consistently maintains levels higher than unity, reflecting the highly asymmetric environment surrounding Eu3+ ions. The estimated elastic limit for both samples was approximately 7 GPa. To assess pressure-induced changes in the local environment, Judd-Ofelt intensity parameters were employed for the calcium alumino silicate glass. The trends observed throughout compression revealed that Ω2 > Ω4 up to 6.8 GPa, while Ω2 < Ω4 for higher pressures, indicating higher covalency between Eu3+ ions and ligands in the elastic domain compared to the plastic domain. The observed increase in Si and Al coordination in the plastic domain was found to play a role in these parameters.

Studies of luminescence traits and Judd-Ofelt analysis of Sm3+ activated oxyfluoride glasses

Novel Sm3+ activated oxyfluoride glass was synthesized via the melt-quenching approach with subsequent heat treatment. The X-ray diffraction measurement discloses the amorphous nature of prepared glasses. And, FTIR illustrates the molar surplus of Bi2O3 raises the network connectivity by creating bridging oxygen sites in the structure. The Judd-Ofelt (J-O) intensity parameters exhibit Ω4>Ω2>Ω6 trend, witnessing the rigidity of the glass structure and ionic bonding between Sm3+ ions and surrounding ligands. The 4G5/2 → 6H7/2 transition of Sm3+ is the most applicable for reddish-orange lasers due to their higher values of radiative transition probability, branching ratio, and stimulated emission cross-section. The optimum emission intensity is obtained with 30 mol% Bi2O3 and the corresponding decay time is 1.40 ms. Additionally, the F30 glass sample was lit in a reddish-orange region having a CCT value of 1689 K. The thermal luminescence quenching of the prepared glass was studied and the thermal stability parameters activation energy was estimated. Further, the contactless optical thermometry capability of the glass sample was explored within the range of 303 K–603 K using the luminescence intensity ratio (LIR) technique. Thus, the above studies on the glass sample suggest that it can be used as an active medium in lasers, contactless optical temperature sensing, and high-energy scintillator applications.

The borophosphate glasses compositions based on (64-x)P2O5-5B2O3-15ZnO-15Li2O-xX-1Sm2O3 (x = 0 & 15; X = CaF2) are prepared by melting and quenched technique. The optical and photoluminescence were obtained from the UV-Vis-NIR spectrophotometer and spectrofluorophotometer. The ground state 6H5/2 as the start transition in the absorption spectrum and the Judd-Ofelt intensity parameters (Ω2, Ω4, and Ω6) were determined. The emission spectra of borophosphate glass with CaF2 were recorded at an excitation of 401 nm which gave four peaks namely 6H5/2, 6H7/2, 6H9/2, and 6H11/2. The results of radiative properties for the 4G5/2 → 6H7/2 transition were found to be higher in the zinc borophosphate glass without fluoride. Based on these results, zinc borophosphate glass can be used as a candidate for the orange laser application.

Broadband near-infrared amplified spontaneous emission of Er3+-doped germanate glass fiber.

Er3+-doped glass and fiber are very attractive for near-infrared (NIR) lasers and photonic applications. In this work, the full width at half maximum (FWHM) of NIR fluorescence emission of the Er3+-doped germanate glass can be broadened from 72 to 99 nm when Al2O3 was added. In addition, the spectroscopic properties, including absorption and emission spectra, Judd-Ofelt intensity parameters, absorption and emission cross sections, gain coefficient, and fluorescence lifetime, of the Al2O3-modified germanate glass were systematically investigated. What is more, silicate-clad heavily Er3+-doped germanate core multimaterial fibers were successfully drawn by a rod-in-tube method. Notably, broadband NIR amplified spontaneous emission (ASE) with an FWHM of 120 nm was achieved in this new fiber. To the best of our knowledge, this is the largest FWHM reported for Er3+-doped germanate glass fibers. These results suggest that the as-drawn Er3+-doped germanate glass fiber with superior performances is a promising candidate for broadband optical amplification.

Additionally, the dominant characteristic peak of Eu3+ was studied through photoluminescence emission under excitation at 472 nm. Lifetime decay analysis and CIE color coordinates were obtained. Judd-Ofelt intensity parameters were calculated based on the emission spectra, elucidating the radiative properties of CKMV:0.05Eu3+. Temperature-dependent photoluminescence demonstrated the good thermal stability of the optimized sample. From the temperature dependent life time analysis, the sensitivity of the material has been calculated. These findings suggest that this phosphor is well-suited for use in solid-state lighting applications.
