Research Abstract

A novel synthesis route to obtain transparent multifunctional ceramics by using SPS has been proposed. Transparent lutetium niobate (Lu3NbO7) had a cubic defect-fluorite structure, where Lu and Nb cations randomly occupy the 4a site, and 1/8 of the 8c site for O anion is statistically defective. Such disordering of cations and O defects makes Lu3NbO7 is an interesting multifunctional material. Transparent Lu3NbO7 ceramics had a uniform microstructure and the transmittance at 550 nm reached at 68%. TEM observation suggests the formation of ordered structure in Lu3NbO7 ceramics.
