TL;DR: An overview of advances in developing new modalities for neural circuitry modulation utilizing upconversion‐nanoparticle‐mediated optogenetics is presented, which have led to minimally invasive optical stimulation and inhibition of neurons with substantially improved selectivity, sensitivity, and spatial resolution.

TL;DR: In this article, a review of spectral converters for photovoltaic energy conversion is presented, with a particular emphasis on lanthanide-based upconversion, quantum-cutting and down-shifting materials.

TL;DR: The utilization of dielectric microbeads are exploited to significantly enhance the photon upconversion processes in lanthanide-doped nanocrystals to enhance the luminescence efficiency of upconverting nanoparticles and show its application for optogenetics.

TL;DR: Tunable resonator-upconverted emission (TRUE) is achieved by placing upconversion nanoparticles (UCNPs) within plasmonic nanoresonators within size-tuned gap-plasmon resonances in Al nanodisk arrays.

TL;DR: It is demonstrated that it is possible to control triplet dynamics by coupling organic molecules to lanthanide-doped inorganic insulating nanoparticles, allowing the classically forbidden transitions from the ground-state singlet to excited-state triplets to gain oscillator strength, enabling triplet excitons to be directly generated on molecules via photon absorption.
