Abstract
- We report an optical study of Tb-doped YO nanocrystals synthesized by Pechini-type sol-gel method. The particles are investigated in terms of size and morphology by means of X-ray diffraction and transmission electron microscopy analysis. It is shown how the simple Pechini method allows for the growth of monocrystalline nanoparticles with a volume-weighted average size of about 30 nm. The optical properties of Tb in the host lattice are studied in terms of PL, PLE, and lifetimes. Moreover, a correlation between the type of decay curves, the emission and excitation bands' shapes, and the site location of the emitting Tb in the host material YOis proposed.
