摘要：

High oxide-ion conducting material delta-Bi2O3 was electrodeposited on stainless steel and polycrystalline Au substrates at low temperature. Both X-ray diffraction (XRD) measurements and transmission electron microscopy (TENT) images revealed nanocrystallites about 100 nm in size inside the electrodeposited delta-Bi2O3 thin films. High-resolution TEM images showed the existence of smaller nanocrystallites 10-20 nm in diameter. The long-term stability of the electrodeposited delta-Bi2O3 was checked by XRD measurements on 1-year-old samples. Its thermal stability was studied through a series of annealing at different temperatures. At an annealing temperature of 340 degreesC, the delta-Bi2O3 fCC Structure begins to change towards that of Sillenite (bcc). (C) 2004 Elsevier B.V. All rights reserved.
