Abstract

Abstract: Lanthanide complexes are excellent luminescent materials with sharp emission bands and good color purity(FWHM<10 nm) as well as high inner-quantum efficiency(about 100%), which is helpful for fabricating bright, efficient and full-color OLEDs. So, the studies on lanthanide ion based electroluminescent devices are very important in application or theoretical researches. The researches on lanthanide ions based OLEDs mainly focus on Eu3+, Tb3+ ions, which have high emission efficiency; and Nd3+, Yb3+, Er3+ ions, which emissions are in the near infrared region. In this paper, mainly lanthanide ions based electroluminescent devices and their developments are reviewed. By dissertating EL properites of different Eu(Ⅲ) and Tb(Ⅲ) complexes, we find that luminescent properties of lanthanide ions are strongly depended on sensitization of ligands; Near-infrared lanthanide complexes(Yb3+, Nd3+, Er3+) have the potential applications in optical amplification, laser systems and biomedicine, etc..
