A review on the luminescence properties of rare-earth ions doped in insulating nanoparticles

International audienceRare-earth ions are unique chemical elements covering a wide range of applications. In particular, they allowed many innovative applications in the field of photonics. In order to develop new features, a growing interest is the use of nanoparticles doped with rare-earth ions, such as nanoparticles used for medical imaging or nanoparticles contained in glass-ceramics. This presentation provides a review on the spectroscopic properties of rare-earth ions in these materials discovered these last twenty years. In particular, we will discuss changes induced by the insertion of rare-earth ions in nanoparticles and the influence of the surrounding glassy matrix. Understanding these different phenomena opens new perspectives for photonics
