Abstract

∶BaF

nanoparticles prepared via co-precipitation have been investigated for reaction sequence and concentration of reactants. Nano-particles were characterized by means of X-ray diffraction

SEM

TEM

ICP respectively. The results indicate that the powder synthesized by the condition of reverse reaction (anionic drip into the cationic) and high F

concentration is single phase and the actual doping value is close to the theoretical value. The transparent ceramic was prepared by hot-pressed way at 900 ℃ and 30 MPa. It can be seen that some closed pores existed in the grains from the picture of cross section. After superficial corrosion

grain boundary could be clearly seen from the microscope images. The X-ray induced luminescence intensity reached a maximum when the doping mole fraction of Ce

was 0.1%

lower than the Ce

content in the crystal.
