摘    要:频率上转换研究在近十年有了突飞猛进的发展,它有着非常好的应用前景。也仍然面临着进一步提高上转换效率的任务。由于Yb^3 能级结构的特殊性,它的引入既可以通过能量转换传递使共掺稀土离子上转换发光有较大增强,又可能不引起较明显的荧光猝灭。因而研究Yb^3 作为敏化中心的上转换敏化是有重要意义的,而把提高上转换效率与提高材料的物化性能结合起来更是上转换研究的应用的当务之急。本文综述了上转换敏化的提出和发展,介绍了在该领域取得的成果,特别是间接上转换敏化的成果。

关 键 词:上转换敏化稀土离子  发光材料  上转换发光  激光激发  镱(Ⅲ)  掺杂

Abstract:The research of frequency up conversion has been developed greatly in recent ten years.In order to achieve its applications,it needs to enhance the up conversion efficiency further greatly,which is the core problem of up conversion.Because of the specialty of Yb 3+ ion energy level,Yb 3+ can greatly enhance up conversion luminescence of co doped rare earth ion activator through energy transfer.Meanwhile it may not cause the obvious fluorescence quenching.Thus it is very significance to investigate up conversion sensitization which Yb 3+ ion acts as a sensitizer.It is more important that it is quite urgent to combine up conversion efficiency and material property to develop up conversion.This paper reviews the proposing and developing process of up conversion sensitization.The achievement of up conversion sensitization field especial the originate fruit in indirect up conversion sensitization obtained by China are introduce emphatically.
Keywords:Direct up  conversion sensitization    Indirect up  conversion sensitization
