Abstract
Ordered ferroelectric neodymium (Nd)-substituted bismuth titanate (Bi 4-xNdxTi3O12) is fabricated on silicon microchannel plates (Si-MCPs). A significantly enhanced photoluminescence peak at about 890 nm (∼1.4 eV) corresponding to the 4 f3 - 4 f3 forced electric dipole transition from the 4I9/2 ground state to different excited states of Nd 3+ is observed. Moreover, the near-infrared emission intensity can be tuned by adjusting the Nd composition. The effects can be ascribed to the difference in the host lattice between the Nd-doped titanate with a simple perovskite structure and the result rendered by the regular cubic array of the Si-MCPs.
