Abstract
⺠Amorphous YAG:Tb phosphor samples can be obtained via a facile sol-gel combustion method. ⺠The photoluminescence intensity decreases under 250 nm excitation with increasing the crystallinity. ⺠The strongest intensity of samples annealed at 800 °C could be obtained with 10% Tb doping. ⺠Red-shifts derive from the deformation of inter-atomic distances within the Tb3+ coordination polyhedron. ⺠A matrix consisting of various amorphous YAG:Tb contents can be applied for an advanced anti-bogus label.
