摘　　要：掺铒材料由于在光放大领域的重要应用引起人们极大的研究兴趣,在掺铒材料中再掺入纳米颗粒能有效增强Er3+的发光强度。综述了各种纳米颗粒对Er3+发光光谱的敏化作用,阐述了纳米颗粒与Er3+之间的能量传递机理,展望了光放大材料的最新发展趋势。Erbium-doped optical materials have attracted considerable attention due to their applications in optical amplification. The luminescence of Er^3＋ can be greatly enhanced by co-doping nanoparticles and Er^3＋ in optical hosts. Different nanoparticles used as sensitizers for erbium-doped materials are discussed, and the mechanism of energy transfer from nanoparticles to erbium ions is also introduced. Moreover, the development trend of optical materials co-doped with nanoparticles and erbium ions is presented as well.
