Migration-based energy storage and luminescence

How can energy migration enhance ND 3+ -sensitized upconversion and downshifting luminescence dynamics?

The use of such energy migration can effectively enhance Nd 3+ -sensitized upconversion and mediate upconversion and downshifting luminescence dynamics with tuning of the rise and decay times 7, 36, 37.

Why is energy migration important?

Energy migration is an essential process in numerous systems, such as natural photosynthetic proteins, artificial polymers, and inorganic optical materials 1, 2, 3.

Which structure produces maximum upconversion luminescence?

The outside-in architecture produces the maximum upconversion luminescence, around 6-times brighter than that of the inside-out at the single-particle level. Monte Carlo simulation suggests a topology-dependent energy migration favoring the upconversion luminescence of outside-in structure.

Does excitation energy affect the luminescence time behavior of nanostructures?

Recent research shows that this does not hold for nanostructures. The luminescence time behavior in the nanomaterials is confirmed seriously affected by the migration process of the excitation energy. This new fundamental insight is significant for the design of functional upconversion nanostructures.

Does topological arrangement enhance upconversion luminescence?

Here, we report an inorganic optical nanosystem composed of NaErF 4 and NaYbF 4, in which topological arrangement enhanced upconversion luminescence. Three architectures are designed for considerations pertaining to energy migration and energy transfer within nanoparticles: outside-in, inside-out, and local energy transfer.

Can lanthanide emitters produce upconversion luminescence through energy migration?

Nature Communications 12, Article number: 3704 (2021) Cite this article Exploration of upconversion luminescence from lanthanide emitters through energy migration has profound implications for fundamental research and technology development.
