“…In the present work, the J–O intensity parameters were calculated using emission spectral transitions 5 D 0 → 7 F 2 , 7 F 4 and 7 F 0 of Eu 3+ ion‐doped PBNS glass and related equations [ 28,29 ] were used to evaluate the JO intensity parameters. The parameters Ω 2 and Ω 4 were calculated in the current work and the values are presented in Table 3 [ 13,30–36 ] ; these values were compared with other reported glass. As the transition 5 D 0 → 7 F 5 cannot be observed in the emission spectrum, the intensity parameter Ω 6 has not been evaluated.…”

Eu3+‐doped‐bismuth‐based phosphate glasses with chemical equation (60 − x)P2O5–20Bi2O3−10Na2CO3–10SrF2–xEu2O3 (PBNSEu), (where x = 0, 0.1, 0.5, 1.0, 1.5 and 2 mol%) were fabricated using the melt‐quenching method. Obtain X‐ray diffraction (XRD), energy‐dispersive X‐ray (EDAX), and Fourier transform infrared (FTIR) spectra were used to characterize the structure of the prepared PBNSEu glass. The J–O (Judd–Ofelt) intensity parameters (Ω2, Ω4) were estimated using photoluminescence emission spectra. When excited with a xenon lamp at λexc = 394 nm, the most intense red‐emission transition occurred at ~612 nm (5D0→7F2). J–O intensity parameters were used to calculate radiative properties, whereas the radiative branching ratio (βR), radiative transition probability (AR), radiative lifetime (τR), and total radiative transition rate (Aτ) were calculated for the transitions 5D0→7FJ (where J = 0–4) and were obtained in the emission spectra for europium ion‐doped in the current glass. Using the CIE1931 chromaticity coordinates axes, the colours of various concentrations of Eu3+ ion‐doped PBNS glass were evaluated using the emission spectra. Temperature‐dependent luminescence spectra were recorded for the optimized PBNSEu20 glass to calculate the activation energy. These results strongly suggested red components in w‐LEDs and visible display laser applications.

“…Therefore, these samples can be used as UV filters and sensors in optical applications. A common peak observed at 405 nm in the absorption spectra of DSW and NSW is due to the 6 H 5/2 -4 F 7/2 transition of Sm 3+ [41]. Several other absorption peaks are visible in the absorption spectra of NSW, which is due to the optical absorption of Nd 3+ .…”

Isovalent substitution of lanthanide ions in Ln 2 WO 6 (Ln = lanthanides) nanoceramics can probe into multifunctional applications due to their unique structural and electronic properties. In this work Sm 3+ ions in the Sm 2 WO 6 nanoceramics were partially replaced with Nd 3+ and Dy 3+ ions and their structural, optical and ionic transport properties were studied. The size and structure of the nanocrystalline LnSmWO 6 (Ln = Nd and Dy) compounds prepared through a combustion method were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy and transmission electron microscopy (TEM). UV-Visible spectroscopy and photoluminescence spectroscopy were used for the investigation of optical and electronic properties of the nanoceramics. Bulk ceramics prepared from the nanoparticles achieved high-density during the sintering process and the surface morphology of the dense NdSmWO 6 was imaged using scanning electron microscopy. The electrical properties of the dense ceramics were analysed using impedance spectroscopy. XRD analysis carried out on the prepared materials showed a single-phase monoclinic structure for the nanoceramics. A combined analysis of FTIR and Raman studies showed the presence of Ln-O and O-W-O vibrations, which confirm the monoclinic structure. Particulate properties investigated through the TEM imaging showed that the prepared materials are polycrystalline aggregates. Optical studies carried out on the nanoparticles showed absorption in the UV region and emission in the visible region. Impedance spectroscopic studies conducted on bulk ceramics imply that these are good oxide ion conductors at high-temperature.

“…The quenching point of glass materials is due to the non-radiative energy transfer through cross-relaxation and resonant energy transfer. As the concentration of Sm 3+ ions increases, the distance between the Sm 3+ ions decreases, and the energy transfer through cross-relaxation also increases [7]. That point indicates the energy transfers of which cross-relaxation and resonant.…”

Sm3+ ion doped TeO2: ZnF2: BaO glasses are prepared in different atmospheres by melt quenching technique. The glasses structure was analyzed using a Rigaku SmartLab SE X-ray diffractometer (XRD). Absorption spectra (Shimadzu, 3600) in the wavelength between 400 to 1800 nm were recorded using a UV-VIS-NIR spectrophotometer. They found a total of seven peaks, which corresponded with the energy transitions of Sm3+ ion from the ground level 6H5/2 → 6F11/2, 6F9/2, 6F7/2, 6F5/2, 6F3/2, 6H15/2, and 6F1/2 at 944, 1083, 1238, 1383, 1485 and 1543 nm respectively. A spectrofluorophotometer (Cary-Eclipse) was used to detect the photoluminescence, and the excitation spectra were obtained from measurements in wavelengths of 300 to 550 nm using the emission spectrum at 597 nm. from 6H5/2 (ground state) → 4D7/2 (345), 4D3/2 (362), 6P7/2 (375), 6P3/2 (403), 6P5/2 (417) 4G9/2 (438), 4I13/2 (462) 4I11/2 (474), 4G7/2 (501) and 4F3/2 (526) the excited states. Using a 405 nm exciting wavelength, the emission spectra were captured in the 500–750 nm. The lifetime of the sample between the sample prepared in the air atmosphere and the CO2 atmosphere at the excitation wavelength of 405 nm was 0.679 and 0.662 ms, respectively.
