采用气溶胶辅助化学气相沉积（AACVD）技术，从一种简单的含单丁基氧化锡和金酸的甲醇溶液中一锅法制备了金/氧化锡复合薄膜。在玻璃上形成两种类型的膜-顶板上的金纳米颗粒膜和加热基板上的Au/SnO 2复合膜。复合膜显示出随着从入口的位置而掺入的不同量的金-使得能够形成梯度膜。这使得能够快速评估膜的功能特性。最佳位置显示了理想的性能，包括蓝色着色和反射率在IR的组合。这项工作表明，TCO膜的颜色可以通过金纳米粒子掺杂剂调整，而不去除TCO性能。
Composite gold/tin oxide films were grown from a simple one-pot precursor solution containing monobutyltin trichloride and auric acid in methanol using aerosol assisted chemical vapour deposition (AACVD). Two types of films were formed on glass - gold nanoparticle films on the top plate and Au/SnO2 composite film on the heated substrate. The composite film showed different amounts of gold incorporation with position from the inlet - enabling a graded film to be formed. This enabled rapid assessment of the films' functional properties. Optimum locations showed a combination of desirable properties including a blue colouration and reflectivity in the IR. This work shows that the colour of TCO films can be tuned by gold nanoparticle dopants without removing the TCO properties.
