Effect of Eu ion incorporation on the emission behavior of Y 2 O 3 nanophosphors: A detailed study of structural and optical properties

Effect of Eu Doping on the Physical, Photoluminescence, and Photocatalytic Characteristics of ZnO Thin Films Grown by Sol–Gel Method

“…Among all the peaks, the most dominant red emissions at 612, 616, and 625 nm are pertaining to the 5 D 0 → 7F 2 transitions of Eu 3+ ion and are assigned to the force electric dipole transitions . The low‐intensity emissions at 581, 587, 594, and 600 nm correspond to 5 D 0 → 7F 0 and 5 D 0 → 7F 1 transitions . The 5 D 0 → 7F 1 transition is a magnetic dipole transition and its intensity hardly changes with the bonding environment of Eu 3+ ion, whereas 5 D 0 → 7F 2 transition is hypersensitive to the coordination environment of Eu 3+ ions .…”

The effects of boric acid on crystal structure, nano-/microstructure and photoluminescence characteristics of rare earth-doped Y2O3/YBO3 composite compounds

“…3d, under the excitation wavelength of 240 nm, a strong band is seen at 592 nm which is related to the magnetic dipole transition of 5 F 2 , only C 1 sites are considered since the C i locations do not contribute to the emission characteristics [23]. As a matter of fact, the optical properties of phosphors depend on wide ranges of parameters.…”

“…Among the lanthanide ions, Eu 3? with 5 D 0 -7 F 2 transition has been used extensively as a source of red light at an approximate wavelength of 618 nm [5].…”

“…It was found that the change in crystal structure leads to the huge differences in the wavelength and the photoluminescence characteristics. The main emission bands of Y 2 O 3 -and YBO 3 -based compounds are attributed to 5 …”

Lanthanide-Doped Y₂o₃ - The Photoluminescent and Radioluminescent Properties of Sol-Gel Prepared Samples

“…Because of similarities in ionic radii with RE ions and its general chemical and radiation stability, Y 2 O 3 presents a suitable host for doping with RE-elements without influencing its crystal structure [9][10][11][12][13][14]. Yttrium oxide (Y 2 O 3 ) exhibits predominantly body-centred cubic structure; however, other Y 2 O 3 phases have been also reported under different external conditions [15,16].…”
