    Photonic structuring improves the colour purity of rare-earth nanophosphors

    No full text
    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.Peer Reviewe
