Strong Eu emission of annealed Y 2 O 3 :Eu nanotube and nano‐sized crystals
We have observed a drastic increase of the Eu 3+ emission intensity by annealing nanotubes and nano‐sized hexagonal‐mesostructured crystals of the Y 2 O 3 :Eu system together with bulk samples. It is found that there are three Eu 3+ sites in all samples. Stark splitting schemes are proposed for the...
