摘要:
Pure hexagonal-phased YBO3:Eu3+ nanocrystals (NCs) including natiosheets (NSs), bundles of nanobelts (NBs) and quasi-spheres composed of nanotubes (NTs) were prepared by hydrothermal method. The results indicate that in NCs, there exist two symmetry sites of Eu3+ ions, the interior (A) and the surface (B), while there exists only one interior site (A) in the bulk. It is important to observe that the electronic transition rate of D-5(0)-Sigma(j) F-7(J) Eu3+ at the surface site is improved 3-5 times than that of the interior site.
