Abstract:

A highly transparent ceramic has been synthesized from Nd(3+):Y(2)O(3) to which 6 mol. \% ZrO(2) and 25 mol. \% Sc(2)O(3) or Lu(2)O(3) were added for disordering the crystal structure. Nanopowders with an average particle size of 10-15 nm served as an initial material. They were compacted by the method of uniaxial static pressing combined with ultrasonic action on nanoparticles. The compacting pressure was 200 MPa; the power of the ultrasonic generator was 1.5 kW. It has been shown that the replacement of Y by isovalent Sc and Lu ions and by heterovalent Zr ions reduces the content of pores and the sizes of crystallites. The transparency of the Nd(3+):Y(2)O(3) ceramic with these additives reaches a maximum of 82.2\%, and the 40\% intensity level spectral band corresponding to the (Lambda)F(3/2)-> (Lambda)I(11/2) transition widens from 11.4 to 40 nm.
