The use of a novel inorganic nanoscale cluster (Al(μ-OH)Co(NH)) was investigated for its utility as a precursor for AlCoOx films. Mixed-metal aluminum and cobalt oxide thin films were solution deposited from the novel cluster solution via the spin-coating method on Si (100) and quartz substrates. The films were annealed at increasing temperatures up to 800 °C, and characterization of these films via TEM and XRD confirms binary CoO crystalline phase present in an amorphous AlO network. Films are relatively smooth (R < 4 nm), polycrystalline, and demonstrate a tunable optical response dominated by CoO with two electronic transitions.
研究了一种新型无机纳米级团簇(Al(μ-OH)Co(NH))作为AlCoOx薄膜前驱体的用途。通过旋涂法将混合金属铝和钴氧化物薄膜从新型团簇溶液中溶液沉积在Si(100)和石英衬底上。这些薄膜在高达800°C的温度下进行退火处理,通过TEM和XRD对这些薄膜进行表征,证实了在非晶AlO网络中存在二元CoO晶相。薄膜相对光滑(R<4nm),为多晶结构,并表现出以CoO为主导的可调谐光学响应,具有两个电子跃迁。
