Up-Conversion Luminescence in Thulium Doped Barium Titanate Inverted Opal
The synthesis, infiltration into a polystyrene opal and luminescence spectroscopy of BaTiO3: Tm3+ were reported in this paper. A photonic band gap and blue up-conversion photoluminescence were achieved in the synthesized inverted opal, respectively demonstrated by reflection spectrum and emission spectrum excited by 650nm laser source at room temperature. Changes of the emission spectroscopy compared with the thulium doped barium titanate reference sample were observed and thus provided evidence for the light inhibition effect of the photonic structure.
