稀土掺杂正交发光纳米晶：从基础到前沿应用.

Lanthanide ion-doped upconversion luminescent nanomaterials with unique nonlinear Anti-Stokes luminescence have broad applications in life sciences, photonic transport, programmable control, and information encoding and decoding. Rare-earth-doped orthogonal luminescent nanocrystals are a major emerging research direction in the field of luminescence in recent years, which is based on the upconversion luminescence mechanism to realize the multifunctional integration of orthogonal luminescence on a single nanoparticle in a reasonable core-shell structure design, broadening the optional range and spatio-temporal tunability of spectra to further promote its application in related fields. This review summarizes the recent progress in the design optimization of synthetic rare-earth-doped orthogonal luminescent nanocrystals, and systematically discusses the regulation process of achieving orthogonal luminescence via energy transfer of rare-earth ions based on core-shell structures construction, as well as presents its applications in frontier fields such as information security anti-counterfeiting, bioimaging and therapy. Furthermore, the current challenges and future prospects of orthogonal luminescence are also summed up. [ABSTRACT FROM AUTHOR]
