文摘
- •
YAG:Eu,Hf single crystals containing only 151Eu isotopes were prepared.
- •
isotopic enriched crystals gave a well-resolved EPR hyperfine structure of Eu2+ centers.
- •
the redox ratio was followed through the Eu2+ associated absorption band at 250 nm.
- •
the band intensities at 378 nm correlate with the Eu2+ concentration.
