Angular emission properties of a layer of rare-earth based nanophosphors embedded in one-dimensional photonic crystal coatings
The angular properties of light emitted from rare-earth based nanophosphors embedded in optical resonators built in one-dimensional photonic crystal coatings are herein investigated. Strong directional dependence of the photoluminescence spectra is found. Abrupt angular variations of the enhancement...
