In this report presented are structure, morphology and luminescence
properties of nanopowders based on gadolinium zirconium oxide (Gd2Zr2O7)
doped by europium ions (Eu3+). The nanopowders were prepared using a flame
combustion method, the most frequently used process due to the simplicity and
low cost of the synthesis procedures and also due to the possibility of
tailoring the size and morphology of particles. The produced material is
suitable for various optical devices. The luminescence properties of
synthesized nanopowders were characterized by emission spectra and
luminescence lifetimes obtained by using the streak camera system. Moreover,
emission spectra were obtained and compared for powders as-obtained and after
additional annealing at 1200o C. Luminescence emission spectra clearly show
peaks characteristic for the strong emission lines at 611 nm and 630 nm
corresponding to the 5D0 ? 7F2 long lived transition.
