Description
Summary:(Bi 0.5 Na 0.5 ) 0.935 Ba 0.065 (Zn 1/3 Nb 2/3 ) x Ti (1− x ) O 3 -0.005Er (BNBT- x ZN-Er) multifunctional ceramics were prepared by a traditional solid-phase reaction method. The ferroelectric, dielectric, and photoluminescence properties of BNBT- x ZN-Er ceramics doped with different (Zn 1/3 Nb 2/3 ) 4+ complex ions were systematically investigated. The results emerge that (Zn 1/3 Nb 2/3 ) 4+ can be completely diffused in the BNBT- x ZN-Er ceramics lattice. With the addition of complex ions, the long-range ferroelectric order of BNBT- x ZN-Er ceramics was significantly disrupted, and the electric field-induced strain responses was promoted. The maximum bipolar strain of 0.35% was obtained by introducing (Zn 1/3 Nb 2/3 ) 4+ with a concentration of x  = 0.0100, corresponding to d 33 * ( S max / E max ) of 500 pm/V. Two dielectric anomaly peaks emerge at T R−E and T m due to the transformation of the phase. Additionally, the ceramics have bright up-conversion photoluminescence properties under a 980 nm laser light source, exhibiting intense green emission bands at 526 and 547 nm. The results illustrate that the BNBT- x Zn-Er ceramics exhibit excellent ferroelectric properties and also obtain bright up-conversion green photoluminescence properties.
