Effect of gold nanoparticles on lead zinc niobate–barium titanate structure by X-ray absorption spectroscopy

© 2017 Taylor & Francis Group, LLC. The 0.93PZN-0.07BT ceramics containing 0.5 wt% AuNPs sintering was carried out for 3–5 h at various temperatures ranging from 1100 to 1150°C. The effect of AuNPs on 0.93PZN-0.07BT local structure and dielectric properties were investigated. The Au K-edge XAN...
