摘要: Abstract Er 3+ /Yb -doped Y(OH) 3 @ β -NaYF 4 core-shell nanorods are synthesized through in situ ion exchange reaction using as templates. Further, inert shells of without activated dopants coated by a facile hydrothermal method. Upconversion intensity increases dramatically reaction, and it can be further enhanced coating shells. The maximal factor reaches 6.58. On the basis structural tests spectral data, formation mechanisms discussed, well their upconversion properties.
