“…Gd 3+ containing host matrices exhibit an interesting spectroscopic phenomenon where the sensitizer Gd 3+ enhances the luminescence of RE 3+ ions when excited by Gd 3+ 's characteristic wavelength. 29,30 The energy transfer from Gd 3+ to other rare earth ions, such as Eu (Er−Tb), results in the emission of two visible photons when excited by high intensity VUV photons. 31 The 4f energy levels of Gd 3+ and Eu 3+ exhibit excellent overlap, which leads to an amplification of the distinctive emissions of Eu 3+ when excited by UV/blue excitation.…”

Herein, we report a strategy to synthesize an Eu 3+ doped singlephase monoclinic K 3 GdF 6 double perovskite via a solid-state route with an average crystallite size of 18 ± 2.00 nm. Characterization methods such as X-ray diffraction, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and spectroscopic techniques provided a thorough understanding of the material's atomic and molecular-level structural, morphological, and functional properties. The photoluminescence study of K 3 GdF 6 :5% Eu 3+ under different excitations such as 273, 393, 405, and 464 nm showed a hypersensitive, intense red emission at 613 nm and orange emission at 590 nm, which is a necessary parameter for high contrast imaging, particularly for overcoming autofluorescent background. The usage of K 3 GdF 6 :5% Eu 3+ for spectral mapping and imaging has been specifically demonstrated through spatial photoluminescence mapping under 405 nm laser excitation. Moreover, the optical studies substantiated the occurrence of quantum cutting in K 3 GdF 6 :Eu 3+ through systematic energy transfer between Gd 3+ and Eu 3+ . Interestingly, in addition to optical attributes, the double perovskite showed superparamagnetic behavior at low temperature (2 K) with an average saturation magnetization of 96.86 emu/g. Through an exhaustive investigation of its optical and superparamagnetic properties, the synthesized double perovskite has been demonstrated to be a feasible choice for bioimaging (including optical and MRI), multiplexing detection, sensing, and other optical technologies.

“…However, Gd 3+ has an upper hand over Ce 3+ as it acts not only as an efficient sensitizer but also as a paramagnetic entity. Gd 3+ containing host matrices exhibit an interesting spectroscopic phenomenon where the sensitizer Gd 3+ enhances the luminescence of RE 3+ ions when excited by Gd 3+ ’s characteristic wavelength. , …”
