dc.description.abstract | Investigation on luminescent lanthanide-doped upconversion (UC) nanocrystals has been focused for many years due to their great application in photonics and photovoltaics. In stark contrast to the conventional luminescent materials such as organic dyes and quantum dots, lanthanide-doped UC nanocrystals own advanced properties which always show as large anti-Stokes shifts, no photobleaching and blinking, high photochemical stability, proposing them to be a promising new class of luminescent materials. In this thesis, an overview of the recent advances on luminescent materials will be given firstly. The luminescence theories of lanthanide ions, backgrounds of lanthanide-doped luminescent nanocrystals will be introduced, followed by the summarization of the recent achievement and limitation of the lanthanide-doped nanocrystal synthesis techniques. This thesis seeks to find a general solution to synthesize lanthanide-doped UC nanocrystals and successfully apply this technique in the fabrication of lanthanide-doped various types of UC host matrix including KMnF3, KYb2F7, NaYF4 and LiYF4. This technique endows these designed lanthanide-doped nanomaterials with unique luminescent properties thus promises them potential applications in biolabeling and bioimage. | |
