| 1 | X-ray-charged bright persistent luminescence in NaYF_(4):Ln^(3+)@NaYF_(4) nanoparticles for multidimensional optical information storage显示文摘NaYF_(4):Ln^(3+),due to its outstanding upconversion characteristics,has become one of the most important luminescent nanomaterials in biological imaging,optical information storage,and anticounterfeiting applications.However,the large specific surface area of NaYF_(4):Ln^(3+)nanoparticles generally leads to serious nonradiative transitions,which may greatly hinder the discovery of new optical functionality with promising applications.In this paper,we report that monodispersed nanoscale NaYF_(4):Ln^(3+),unexpectedly,can also be an excellent persistent luminescent(PersL)material.The NaYF_(4):Ln^(3+)nanoparticles with surface-passivated core–shell structures exhibit intense X-ray-charged PersL and narrow-band emissions tunable from 480 to 1060 nm.A mechanism for PersL in NaYF_(4):Ln^(3+)is proposed by means of thermoluminescence measurements and host-referred binding energy(HRBE)scheme,which suggests that some lanthanide ions(such as Tb)may also act as effective electron traps to achieve intense PersL.The uniform and spherical NaYF_(4):Ln^(3+)nanoparticles are dispersible in solvents,thus enabling many applications that are not accessible for traditional PersL phosphors.A new 3-dimensional(2 dimensions of planar space and 1 dimension of wavelength)optical information-storage application is demonstrated by inkjet-printing multicolor PersL nanoparticles.The multicolor persistent luminescence,as an emerging and promising emissive mode in NaYF_(4):Ln^(3+),will provide great opportunities for nanomaterials to be applied to a wider range of fields. | Yixi Zhuang Dunrong Chen Wenjing Chen Wenxing Zhang Xin Su Renren Deng Zhongfu An Hongmin Chen Rong-Jun Xie | 2021 | Light(Science & Applications)2021，10，7： | 12 |
