Abstract

The new complex Tb0.5 Eu0.5 (TTA)3Dipy was synthesized. By doping polymer PVK with Tb0.5 Eu0.5 (TTA)3Dipy, the EL device was fabricated with the structure of ITO/PVK: Tb0.5 Eu0.5 (TTA)3Dipy/PBD/Al using PVK: Tb0.5 Eu0.5 (TTA)3Dipy as the emitting layer. Compared with the blend PVK: Eu(TTA)3, the Tb3+ acts as an energy transfer bridge, which enhances the energy transfer efficiency between PVK and Tb0.5 Eu0.5 (TTA)3Dipy. As a result, the emission of Eu3+ is enhanced with the quenching of the emission of PVK. The process of energy transfer was studied.

Abstract

Ca2BO3Cl:Ce3+, Ca2BO3Cl:Tb3+, and Ca2BO3Cl:Ce3+, Tb3+ phosphors are synthesized by a high temperature solid-state reaction. The emission intensity of Ce3+ or Tb3+ in Ca2BO3Cl is influenced by the Ce3+ or Tb3+ doping content, and the optimum concentrations of Ce3+ and Tb3+ are 0.03 mol and 0.05 mol, respectively. The concentration quenching effect of Ce3+ or Tb3+ in Ca2BO3Cl occurs, and the concentration quenching mechanism is d-d interaction for either Ce3+ or Tb3+. The Ca2BO3Cl:Ce3+, Tb3+ can produce colour emission from blue to green by properly tuning the relative ratio between Ce3+ and Tb3+, and the emission intensity of Tb3+ in Ca2BO3Cl can be enhanced by the energy transfer from Ce3+ to Tb3+. The results indicate that Ca2BO3Cl:Ce3+, Tb3+ may be a promising double emission phosphor for UV-based white light emitting diodes. [ABSTRACT FROM AUTHOR]
