In biomedical science luminescent nanomaterials could make flouorescent labelling possible and effective. Notably in the last few years many types of nanomaterials have become the current subjects of basic and applied research such as nanomaterials containing rare-earth upconversion nanophosphors UCNP . When stimulating this materialby infrared light radiant emission will be aborted in the visible region. Therefore they have become one of the new and recognized research objects in many sectors such as health care security energy . When applying in the health care sector the UCNP has two specific advantages compared to other luminescent materials. First of all using infrared stimulation sources minimizes the object s self-emitting ability and enhances the contrast of micro-images. In addition infrared light is safer for human body
