Paper Title:
Enhancement of Luminescent Properties of Sol-Gel-Derived BaTiO3: Pr
  Abstract

Praseodymium (Pr3+)-doped BaTiO3 was synthesized by a high concentration sol-gel process and sintered at different temperatures from 800oC to 1200oC. The emission was due to intra-4f transitions of Pr3+ which were mainly from the excited states 3P0 and 1D2 to the ground states of 3H4 of Pr3+, respectively. Enhancement of the luminescent properties of Pr-doped BaTiO3 was also investigated via adding Mg. For BaTiO3: Pr phosphor added with 0.5 mol% Mg, the emission intensity was about 60 times higher than that of samples without Mg addition. The emission enhancement may caused by the improved crystallinity, the charge compensation and the change of the substitution site of Pr3+ with the addition of Mg.
