Especially, much effort has been devoted to the synthesis of micronanocrystals doped with lanthanide ions, since Bhargava et al. reported that ZnS: Mn 2 nanocrystals yielded high luminescence efficiencies. Since 2005, when we proposed a general strategy for nanocrystal synthesis via a liquidsolidsolution process, a range of monodisperse and colloidal lanthanidedoped fluoride, oxide, hydroxide, orthovanadate, thiooxide, borate, and phosphate nanocrystals have been successfully prepared.
The unique luminescent properties render Ln 3doped nanocrystals particularly useful in the fields of optical devices and biomedicine, such as displays, immunoassays, and ant counterfeiting.
Here, the application of typical Ln 3doped nanocrystals has been summarized in Table 1 [2, 8, 1221. Because of the potential applications of lanthanidedoped nanocrystals in display devices, optical communication, solidstate lasers, catalysis, and biological labeling, the controlled synthesis of these new nanomaterials has sparked considerable interest.
