摘要Monodisperse beta-NaYF4:Yb3+, Tm3+ (NYF) hexagonal microplates with efficient near-infrared (NIR)-to-NIR up-conversion (UC) developed via a new ion-exchange modified hydrothermal method are reported. Ion exchange modification (IEM) not only significantly increases the UC intensity by up to 1000 times and prolongs the emission lifetimes of Tm3+ and Yb3+, but also enables the monodisperse morphology and size of hexagonal microplates to be maintained. A high UC quantum efficiency (QE) of 3.1% is obtained for IEM beta-NaYF4: 20%Yb3+, 1%Tm3+ when excited with 980 nm light at a power density of 10W cm(-2). The UC emission properties can be finely tailored by changing the NaF/NYF molar ratio (NYF represents lanthanide doped beta-NaYF4) and the doping concentration of Tm3+. The two photon NIR UC emission centered at B803 nm (arising from Tm3+:3H(4)-3H(6)) dominates the UC emission spectrum and high concentrations of Tm3+ favor NIR UC further. A proof-of-concept optical image of printed patterns is demonstrated to verify their applications in security. These results suggest the promising applications of the newly developed monodisperse beta-NaYF4:Yb3+, Tm3+ hexagonal microplates in security, luminescent labels, solid-state lasers, amplifiers, and biomedicine.
