Time and spatially resolved luminescence of nanomaterials

The key luminescence properties of rare earth doped nanoparticles, embedded in a transparent matrix, are studied by means of time- resolved spectroscopey and spatially resolved cathodoluminescence in a scanning electron microscope. Variations between particles are evaluated in terms of luminescence spectrum, lifetime, effiency and energy transfer. Yhe effect of particle embedding is studied by evaluation of the particle-matrix interface.
