Enhancement of Luminescence of YPO sub(4):Eu super(3+),Yb super(3+) Nanophosphor Synthesized by Hydrothermal Method

YPO sub(4) nanowires (NWs) and nanoparticles (NPs) have been synthesized by hydrothermal methods respectively in the absence and presence of EDTA. The Eu super(3+) and Yb super(3+) codoped YPO sub(4) NWs and NPs prepared directly from hydrothermal systems show efficient red down-conversion luminesce...

Summary:YPO sub(4) nanowires (NWs) and nanoparticles (NPs) have been synthesized by hydrothermal methods respectively in the absence and presence of EDTA. The Eu super(3+) and Yb super(3+) codoped YPO sub(4) NWs and NPs prepared directly from hydrothermal systems show efficient red down-conversion luminescence (DL) and upconversion luminescence (UL) at room temperature without further annealing process. EDTA plays a critical role in controlling the morphologies of YPO sub(4) nanocrystals in hydrothermal systems and enhances both the DL and UL intensities of Eu super(3+) by the factor of 100%. Monodispersed Eu super(3+) and Yb super(3+) codoped YPO sub(4) NPs will be a new candidate for application in infrared displays and biological labels.
