Luminescence of Y₃Al₅O₁₂:Eu³⁺ nanophosphors in blood and organic media

Study on the Local Structure and Luminescence Properties of a Y2Mg2Al2Si2O12:Eu3+ Red Phosphor for White-Light-Emitting Diodes

“…Because of the effect of the crystal field and the change of the local symmetry, the spectral lines of activator ions may be split to different degrees, and the relative intensities of the transitions may change accordingly. In some reports, an intense 5 D 0 → 7 F 4 transition is often found in matrix material that has D 4 d geometric symmetry. , The very high intensity of the 5 D 0 → 7 F 4 transition was reported in garnet structural Ca 3 Sc 2 Si 3 O 12 :Eu 3+ and YAG:Eu 3+ with D 2 point symmetry. , So, the further development of garnet structural red phosphors is feasible. Moreover, it is important to lucubrate the corresponding relationship between the crystal structure and spectral characteristics of the relevant materials for their design, modification, and application.…”

Eu3+-doped ratiometric optical thermometers: Experiment and Judd-Ofelt modelling

“…The prepared particles were collected by centrifugation at 2800 rpm for 5 min repeated 3 times. The resulting washed precipitate was dried in an oven at 110 o C. Nanocrystalline Y3Al5O12:Eu 3+ 4 at.% (YAG:Eu 3+ 4 at.%) sample was prepared using the modified Pechini method based on additional heat treatment of the amorphous precursor in a molten salt [32]. Briefly, the citrate complexes of Y 3+ , Eu 3+ and Al 3+ are crosslinked with ethylene glycol to form a polymer gel, which was then calcinated at 850 o C for two hours.…”

Multimode high-sensitivity optical YVO4:Ln3+ nanothermometers (Ln3+ = Eu3+, Dy3+, Sm3+) using charge transfer band features

“…Ln 3+ -doped YVO 4 nanocrystalline powders (Ln 3+ = Eu 3+ , Dy 3+ , Sm 3+ ) were prepared via modified Pechini method, which has been previously used for synthesis of various oxides systems activated by rare earths ions [27][28][29] . The prepared samples were studied in the powder form.…”
