Abstract

In this paper, undoped and Ti-doped V2O5 thin ﬁlms were fabricated and deposited onto glass substrates using a «doctor blading» method. Then, the effects of Ti-doping on the optical properties of the thin ﬁlms were investigated. Titanium doping concentration of 0.25-0.75 at.% has been investigated. After treatment in air at different temperatures, the obtained films was characterised by various techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoluminescence (PL). It was found that the as-obtained doped films possessed thermochromic properties and optical switching characters. According to optical tests, thin linings of vanadium dioxide alloyed with Ti have optical properties that are effective for application. Because of their capacity to automatically control interior solar irradiation, lower air-conditioning energy consumption, and maintain a comfortable internal thermal climate, smart windows have drawn increased interest in recent years. The doping strategy and integrating with functional coatings can regulate the properties of obtained V2O5 ﬁlms.

钛掺杂V的光学和物理化学性质研究₂O₅ 纳米薄膜

在本文中，使用“刮刀”方法制备了未掺杂和Ti掺杂的V2O5薄膜，并将其沉积在玻璃基板上。然后，研究了Ti掺杂对薄膜光学性能的影响。研究了0.25～0.75at.%的钛掺杂浓度。在不同温度的空气中处理后，通过扫描电子显微镜（SEM）、X射线衍射（XRD）和光致发光（PL）等各种技术对所获得的薄膜进行了表征。结果表明，所制备的掺杂薄膜具有热致变色性能和光开关特性。根据光学测试，钛合金化的二氧化钒薄衬里具有有效应用的光学性能。近年来，由于智能窗户能够自动控制室内太阳能照射，降低空调能耗，并保持舒适的室内热气候，因此越来越受到人们的关注。掺杂策略和与功能涂层的集成可以调节所获得的V2O5薄膜的性能。
