摘 要:Er^3+-doped SrBi4Ti4O15-Bi4Ti3O12(SBT-BIT-xEr^3+,x=0.00,0.05,0.10,0.15 and 0.20)inter-growth ceramics were synthesized by the solid-state reaction ***,electrical and up-conversion properties of SBT-BIT-xEr^3+ were *** samples showed a single phase of the orthorhombic *** spectroscopy indicated that the Er^3+ substitution for Bi^3+ at A sites of the pseudo-perovskite layer increases the lattice distortion of SBT-BIT-xEr^3+ *** substitution of Bi^3+ by Er^3+ leads to a decrease of dielectric loss tanδ and an increase of conductivity activation *** constant d33 was slightly improved,but dielectric constant was decreased with the Er^3+ *** SBT-BIT-xEr^3+ ceramic with x=0.15 exhibits the optimized electrical behavior(d33~17 pC/N,tanδ~0.83%).Moreover,two bright green(532 and 548 nm)and one red(670 nm)emission bands were observed under the 980 nm *** emission intensity was also obtained when x=0.15 for the SBT-BIT-xEr^3+ ***,this kind of ceramics ought to be promising candidates for multifunctional optoelectronic applications.
