Abstract
Current solid-state lighting technology is built on rare-earth-based phosphors. However, their large crystal size impedes the tuning, optimization, or manipulation of emitted light. Herein we demonstrate this can be achieved combining nanophosphors and nanophotonic architectures. Rare earth emitters are central for many applications related to the generation of light because these nanomaterials feature exceptional thermal and chemical stability. Nevertheless, such stability entails an intrinsic complexity to alter their emission properties. The most common route to control the luminescence spectrum of nanophosphors is thus modifying their chemical composition, which often comes at the expense of deteriorating the performance of the emitter. In this paper, we show that the integration of rare-earth nanocrystals, i.e. nanophosphors, in devised optical environments allows a fine control over the features of the emitted light, without modifying the chemical compositio
