Photonic structuring improves colour purity of rare-earth nanophosphors


D. Geng, E. Cabello-Olmo, G. Lozano, Hernán Míguez Materials Horizons 2018, Vol. 0, DOI: 10.1039/C8MH00123E

Nanophosphor integration in an optical cavity allows unprecedented control over both the chromaticity and the directionality of the emitted light, without modifying the chemical composition of the emitters or compromising their efficiency. Our approach opens a route towards the development of nanoscale photonics based solid state lighting.
