摘　　要：金红石相二氧化钛(rutile TiO₂)作为一种重要的半导体材料,因其优良的化学稳定性、光电化学活性和光学特性,在光电子器件、光催化和环境净化等领域展示了广泛的应用潜力,尽管其在紫外光区域具有良好的光吸收能力,但其带隙能量较大,导致其主要吸收紫外光,而在可见光区域的光吸收效率较低,限制了其在可见光驱动的光催化和光电子器件中的应用效率。对此,本文分析了微观视角下金红石相二氧化钛表面吸附分子的作用机理,并分析了其对光学性能所产生的影响机制及实际应用价值,以期为设计和制备具有特定光学性能的金红石相二氧化钛材料提供理论依据和技术支持。rutile titanium dioxide(rutile TiO2)is an important semiconductor material.Due to its excellent chemical stability,photoelectro-chemical activity and optical properties,it has shown a wide range of application potential in the fields of optoelectronic devices,photocatal-ysis and environmental purification.Although it has good light absorption ability in the ultraviolet region,its large band gap energy leads to its main absorption of ultraviolet light,while its low light absorption efficiency in the visible region limits its application efficiency in visible light driven photocatalytic and optoelectronic devices.In this paper,the mechanism of adsorption molecules on the surface of rutile phase titanium dioxide from the microscopic perspective is analyzed,and its influence mechanism on optical properties and practical application value are analyzed,in order to provide theoretical basis and technical support for the design and preparation of rutile phase titanium dioxide materials with specific optical properties.
