Enhancement of Luminescence of YPO₄:Eu³⁺,Yb³⁺ Nanophosphor Synthesized by Hydrothermal Method

Abstract:

YPO₄ nanowires (NWs) and nanoparticles (NPs) have been synthesized by hydrothermal methods respectively in the absence and presence of EDTA. The Eu³⁺ and Yb³⁺ codoped YPO₄ 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 YPO₄ nanocrystals in hydrothermal systems and enhances both the DL and UL intensities of Eu³⁺ by the factor of 100%. Monodispersed Eu³⁺ and Yb³⁺ codoped YPO₄ NPs will be a new candidate for application in infrared displays and biological labels.
