摘要: Abstract We have produced Bi 12 SiO 20 (BSO) thin films using the sol–gel process. The stable sol was synthesized Bi(NO 3 ) ·5H 2 O and Si(OC H 5 4 (TEOS) as precursors, acetic acid 2-ethoxyethanol solvents, ethanolamine stabilizer. stability of solution, which depends on concentration R h value ( = [H O]/[M]), directly affects microstructure BSO film. determined that optimal for preparation is 0.76 M. influences substrates, annealing temperature, = value solution were investigated. X-ray diffraction (XRD) showed starts to form at 500 °C single-phase polycrystalline are formed 700 °C. coated characterized by means (XRD), scanning electron microscopy (SEM) atomic force (AFM).
