Enhancement of single upconversion nanoparticle imaging by topologically segregated core-shell structure with inward energy migration

HIGHLIGHTS

  • who: Yanxin Zhang from the (UNIVERSITY) have published the article: Enhancement of single upconversion nanoparticle imaging by topologically segregated core-shell structure with inward energy migration, in the Journal: (JOURNAL) of 26/Oct/2021
  • what: The authors report an inorganic optical nanosystem composed of NaErF4 and NaYbF4, in which topological arrangement enhanced upconversion luminescence. The authors reason that there are more sensitizers in excited_states at higher irradiation, reducing the effect of energy loss in migration and the quenching of back energy transfer from acceptors to sensitizers.
  • future: More sophisticated spatial aware numerical methods . . .
