摘要：

Bi4-xPrxTi3O12 thin films were prepared by a chemical solution deposition method and their photoluminescence properties are investigated. The layered perovskite structure of the films is not destroyed by substituting Bi with Pr. The emission lines at 493, 533 and 612 nm are observed, and they can be assigned to the transitions of 3P03H4, 3P03H5 and 1D23H4 of Pr3+ ions. The quenching concentrations are identified to be x = 0.09 and 0.03 for the emissions at 493 and 612 nm. The crystal field plays a crucial role in the luminescence properties of Bi4-xPrxTi3O12 thin films.
