Synthesis and Photoluminescence of Ln3+ Doped TiO2 Nanocrystal

摘要：

Eu<3+> doped TiO<,2> nanocrystals were prepared by the hydrothermal method and characterized by XRD, ESEM, IR, UV absorption and emission spectra. XRD and ESEM micrograph revealed that the samples are in pure rutile phase. Emission spectra under 355nm radiative were measured to characterize the spectroscopic properties, which showed that the samples probably contain trace Tb<3+> ions. The energy transfer mechanism from ruffle TiO<,2> to the 4f shell of Tb <3+> and Eu<3+> was discussed in connection with the excitation and emission properties of the samples.
