Ca2Li2BiV3O12∶Eu3+荧光粉的制备和发光性能
Synthesis and Luminescent Properties of Ca2Li2BiV3O12∶ Eu3+ Phosphor
摘要
Abstract
A novel red phosphor Ca2Li2BiV3O12: Eu3+ was synthesized by solid-state method and characterized by X-ray diffraction ( XRD) and fluorescence spectrophotometer. The influence of synthesis temperature and the concentration of Eu3 + ions, on phase compositions and luminescent properties were systematically investigated. The results show that the Ca2Li2BiV3O12: Eu3+ phosphor with high purity and crystallinity can be obtained at 650 ~ 700℃. The excitation band of the phosphor prepared covers 200 ~400 nm, the emission spectra are described by the well-known 5D0→7FJ(J = 1, 2, 3, 4) emission lines of the Eu3 + ions, the sample prepared with the Eu3 + mole fraction of 14% has the highest emission intensity. This phosphor shows a strong red emission centered at 612 nm under near-UV light and may be applied for white light-emitting diodes.关键词
