Transparent yttria ceramics were fabricated by sintering a mixture of 1 at.% Nd:Y 2 O 3 and HfO 2 nanopowders produced by laser synthesis method. The best transmittance was 80.96% at the wavelength of λ=1080 nm in 6 mol.% HfO 2 doped sample (1.5 mm thick). The additives of hafnium broaden both pumping and luminescence bands of Nd 3+ ion in yttria ceramics. The luminescence intensity of 4 F 3/2 → 4 I 11/2 transition was little affected by hafnium concentration. The effective lifetime of 4 F 3/2 level in Nd:Y 2 O 3 ceramics enhanced by 30% at 10 mol.% HfO 2 doping concentration and the decay kinetics of laser transition attains Förster's behavior.
