摘要：

Monodisperse Er3+:NaGdF4@Ho3+:NaGdF4@NaGdF4 active-core/active-shell/inert-shell nanocrystals, which can extend the near-infrared wavelength excitable range for upconversion (UC) emissions, were successfully fabricated for the first time. Importantly, doping of Er3+ and Ho3+ into the core and shell respectively suppresses adverse energy transfers between them, resulting in intense UC emissions for both Er3+ and Ho3+ dopants.
