Progress on the nano-structural luminescent materials doped with rare-earth ions

Nano-structural luminescent materials doped with rare-earth ions have attracted a great deal of interest because of their potential applications in light-emitting diodes,displays,biological assays,optoelectronic devices with nanometer dimensions,zero-threshold lasers and so on.The progress on the nano-structural luminescent materials such as fluorides,phosphates and oxides doped with rare-earth ions was reviewed in this paper.
