Research Progress of Long-Wavelength Afterglow Luminescent Materials Doped with Transition Metal Ions

区别于稀土离子掺杂长波长余辉发光材料,过渡金属离子掺杂长波(600~1300 nm)长余辉发光材料因其稳定高效的宽带发光被应用于生物成像和药物输送等领域,特别是在生物成像领域被广泛研究。近年来,这一领域的基础研究和应用探索取得了长足的进步,但余辉性能仍然有待提高。主要以发光中心离子为线索总结了近年来报道的过渡金属离子掺杂长波长余辉发光材料,讨论了其余辉性能的优化途径,并介绍了过渡金属离子掺杂长波长余辉发光纳米探针在生物医学领域的应用。最后,对目前相关研究的发展前景进行了展望。

Different from rare earth ion-doped long-wavelength afterglow luminescent materials,transition metal ion doped long-wave(600~1300 nm)afterglow luminescent materials are used in biological imaging and drug delivery fields because of their stable and efficient broadband luminescence,and are widely studied especially in the field of biological imaging.In recent years,the basic research and application exploration in this field have made great progress,but the afterglow performance is far from meeting current requirements.This article mainly uses the luminescence center ion as a clue to summarize the transition metal ion doped long-wavelength afterglow luminescent materials reported in recent years,discusses the optimization of the afterglow performance,and introduces the application of transition metal ion doped long-wavelength afterglow luminescence nano probe in the field ofbio-medicine.Finally,look forward to the development prospects of current research.
