Effect of confinement on the Eu3+ emission band 5D0→7F0 in Eu3+-doped nano-glass-ceramics

Simultaneous luminescence modulation and magnetic field detection via magneto-optical response of Eu3+-doped NaGdF4 nanocrystals

“…According to Judd-Ofelt theory, only the J-J mixing can introduce small intensity of this transition due to the selection rules in theory of rare earth f-f transition. [27][28][29] Indeed, it is precise because the 5 D 0 to 7 F 0 transition will not be spilt by crystal and external fields, and this transition is believed to be only related to the state of J-J mixing. It promises a special optical probe for the external fields which will affect the state of J-J mixing.…”

Interpretation of europium(III) spectra

“…Site-selective spectroscopy can excite single sites, but it is difficult to get an overall picture of the glass structure. Eu 3+ can be used to monitor the partial crystallization of glasses and the formation of glass ceramics [639][640][641][642][643][644][645]. [646].…”

The influence of high magnetic field on electric-dipole emission spectra of Eu3+ in different single crystals

“…In the commonly accepted theory of Judd and Ofelt, 9,10 the effect of a magnetic eld on PL of rare-earth elements was considered rather weak due to the even parity of the magnetic eld, so the magnetic eld does not affect the intensity of optical transitions, in particular, the PL bands of rare-earth ions. However, in recent work reported by Tikhomirov et al about the effect of an external magnetic eld on the PL intensity of Er 3+ -doped crystalline materials, [11][12][13][14] the authors found that the PL of Er 3+doped nanoparticles varied with the external magnetic eld and temperature. The integrated intensity of emission located at about 550 nm decreased with the external magnetic eld, and the Er 3+ -doped nanoparticles were proposed as optical detectors of magnetic elds.…”
