چکیده انگلیسی
The nano-structure BaTiO3 (BT) powder doped with different concentrations of Nd3+ ions were annealed at 750 °C for 1 h to form nano-structure tetragonal phase of BT powder. The structure properties studied using XRD and FTIR methods. Sensitized up-conversion luminescence observed under excitation of 808 nm diode laser, suggesting that the Nd3+ ions-doped BT might be an ideal up-conversion material for infrared excitation. The influence of increasing the concentration of the Nd3+ ions on the luminescence intensity investigated using laser diode. The up-conversion mechanisms in the doped system will be discussed by analyzing the energy level structures of the Nd3+ ions.
