| Rezumat | ||||||
The highly efficient yttrium aluminum garnet (Y3Al5O12 or YAG) and terbium
aluminum garnet (Tb3Al5O12 or TAG) were prepared by solid state reaction (SSR). Particle
distribution was very narrow and homogenous by using multilevel sieve after chemical route.
Luminescence properties were improved and optimized by co-doping TAG with 2 activators:
Ce
3
and Eu3
. Introducing Eu3
in the host lattice of TAG: Ce is more effective than in
YAG:Ce. Luminescence mechanism and the role of Tb in the host lattice as a sensitizer are
discussed.
