一般描述
Germanium(IV) ethoxide is a high-purity, colorless to pale yellow liquid organometallic compound with a trace metal purity of ≥99.95%. It is widely used as a catalyst and a precursor for solution-based and vapor-phase deposition processes, such as sol-gel synthesis, chemical vapor deposition (CVD), and atomic layer deposition (ALD). Its excellent volatility, reactivity, and metal-organic composition make it suitable for producing high-quality germanium-containing films, coatings, and nanostructures in electronics, optics, and semiconductor industries.
应用
溶胶-凝胶中间体，用于光纤和光敏 SiO2-BeO2 玻璃。
Germanium(IV) ethoxide can be used as:
- A precursor in the synthesis of germanium oxide nanostructures via photonic curing.
- A key dopant precursor in the synthesis of Ge-doped hematite photoanodes for enhancing charge separation efficiency in photoelectrochemical water splitting.
- A germanium source to synthesize the bismuth germanate via the sol-gel process, to develop uniform thin films suitable for advanced applications.
