Method for preparing titanium oxide/silicon oxide antireflection film on aluminum oxide transparent ceramic substrate
The invention relates to a method for preparing a titanium oxide/silicon oxide antireflection film on an aluminum oxide transparent ceramic substrate. Common aluminum oxide transparent ceramic, tetrabutyle titanate (Ti(OC4H9)4), tetraethyl orthosilicate ((C2H5)4SiO4), acetic acid (CH3COOH), concentrated nitric acid (HNO3), alcohol (CH3CH2OH), hydrochloric acid (HCL) and deionized water (H2O) are adopted as raw materials, the aluminum oxide transparent ceramic serves as the substrate, a sol-gel method is adopted, parameters such as the film layer thickness, the annealing temperature and the titanium ion concentration are regulated, and then the titanium oxide/silicon oxide two-layer antireflection film is prepared. The novel aluminum oxide transparent ceramic plated with the titanium oxide/silicon oxide two-layer antireflection film has higher light transmittance, is good in interface bonding, and can be used as a core part, a luminescent electric arc tube, of a high pressure sodium lamp, be widely applied to the illumination field and greatly improve the energy utilization rate.
