文摘

class="label">•: Glass/Bi₂O₃/Sb₂O₃ and glass/Sb₂O₃/Bi₂O₃ sandwich heterostructures were prepared.
class="label">•: The heterostructures were compared with the corresponding individual oxide layers.
class="label">•: Bi₂O₃ deposits amorphous on glass, but polycrystalline when overlapping with Sb₂O₃.
class="label">•: Energy bandgap, E_g of glass/Sb₂O₃/Bi₂O₃ is lower than for the individual layers.
class="label">•: E_g of glass/Bi₂O₃/Sb₂O₃ is generally higher than that of the individual layers.
