Abstract:
      Porous yttrium oxyfluoride (YOF︰Yb3+,Ho3+) doped with rare earth ions was prepared by coprecipitation method. Their morphology, phase structure, fluorescence properties, adsorption capacity and surface wettability were analyzed. The results show that nanoparticles have the characteristics of small size and high homogeneity. The fluorescence emission ability drops gradually with increase of Ho3+ with a long fluorescence lifetime. The surface area of porous particles calcined is 413.67 m2/g, which have excellent adsorption performance and surface wettability.
