Lanthanide-doped nanoparticles as the active optical medium in polymer-based devices

The luminescence of lanthanide ions in organic environment is greatly reduced compared to inorganic materials. This thesis describes the doping of the lanthanide ions in the core of inorganic nanoparticles that are soluble in organic solvents as a way to shield the lanthanide ions from the organic environment and thus to increase the luminescence properties
