Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Transparent yttria ceramics were fabricated by sintering a mixture of 1 at.% Nd:Y₂O₃ and HfO₂ nanopowders produced by laser synthesis method. The best transmittance was 80.96% at the wavelength of λ=1080 nm in 6 mol.% HfO₂ doped sample (1.5 mm thick). The additives of hafnium broaden both pumping and luminescence bands of Nd₃₊ ion in yttria ceramics. The luminescence intensity of ₄F_3/2→₄I_11/2 transition was little affected by hafnium concentration. The effective lifetime of ⁴F_3/2 level in Nd:Y₂O₃ ceramics enhanced by 30% at 10 mol.% HfO₂ doping concentration and the decay kinetics of laser transition attains Förster's behavior.
