用直流磁控溅射技术在玻璃基底上沉积TiNxOy薄膜.应用XRD与SEM表征了TiNxOy,薄膜的晶化程度及表面形貌.在室温下300～900 nm的波长范围内测量了薄膜的透射光谱,并根据"包络法"理论,计算了薄膜的光学常数.结果表明,随着入射波长的增加,薄膜的折射率n先减小后再增加;消光系数k单调增加;而吸收系数变化平缓.由"包络法"和Tauc关系确定TiNxOy,薄膜的光学能隙约为2.213 eV.

Spectral selective absorbent film is a crucial factor for the solar heating device. There are many kinds of spectral selective absorbing film made by different ways. TiNxOy thin film with excellent spectral selecting absobent property were successfully prepared by DC magnetron sputtering with Ar as working gas, N2 and O2 as reactive gas, 99.9titanium as the target and is copper slice as the substrate. In this article, the optical characteristics and microstructure of TiNxOy thin film were studied. Inputing O2 can decrease the reflection of the visible lights, and double layer film can get good absorption for solar energy.
