Novel transparent ceramics of Zr4+ doped Ba(Mg,Ta)O3(BMT)with a high refractive index of 2.037 at 587.56 nm were successfully fabricated via high temperature solid-state-reaction sintering method.To make it transparent,the pure cubic Ba(Zr,Mg,Ta)O3 phases(BZMT)were realized in advance by skillfully modulating the lattice structure of BMT from trigonal symmetric to cubic symmetric through doping Zr4+ into the lattice of BMT crystal.Highly optical transmittance of 74% at 650 n,,which hit the upper limit of the theory,was achieved for BZMT.Both abbe number of 23.4 and the bandgap Eg of 3.22 eV have been calculated. 展开更多
