Pr 3+ doped SrBi2Ta 2O9 (SBTO) bismuth layered ferroelectrics are examined in this work. It is demonstrated that a certain amount of Pr 3+ doped ceramic sample shows a strong red and green photoluminescence with blue excitation at room temperature. Photoluminescence excitation spectra show that the samples have broad blue excitation band. This blue band attributes to the f-f transitions from the 3 H4 ground state to the
