Rezumat:

Nanocrystalline YAG powders doped with Er3+, Eu3+ or Tb3+ were synthesized through a citrate-nitrate sol-gel process. Thermal treatments were applied at successively increasing temperatures in the interval 600-1400°C. The structural transformations were monitored by XRD, FT-IR and optical spectroscopy. A pure garnet phase was observed for annealing temperatures higher than 930°C.
