TiO₂-ZrO₂ composite coating was prepared onto glass substrate via sol-gel dip-coating technique using aquo-based titanium(IV) oxysulphate (TOS) and zirconium(IV) n-propoxide (ZP) as the precursor sources of TiO₂ and ZrO₂, respectively followed by calcination at 500^oC/1 h. The samples were characterized by FTIR, Raman, UV/visible/ NIR, GIXRD, FESEM, TEM and XPS studies. The thickness and RI of the coating were measured ellipsometrically. The coated glasses with coating thicknesses of 110±10 nm having refractive index of 1.95±0.05 were found to be uniform with good hardness (≥3H) and adhesion properties. The bonding nature of Ti-O and Zr-O was confirmed by FTIR and XPS analyses while Raman and GIXRD studies revealed the crystalline nature of TiO₂-ZrO₂ composite. FESEM and TEM images revealed crack-free and spider web-like nature of the deposited coating, respectively. The coated TiO₂-ZrO₂ composite showed >20% of average reflection within wavelength range of 350-2500 nm. The above nanocomposite based coated glass could be used as heat reflecting window for efficient energy saving building components.

以水基硫酸氧钛(TOS)和正丙氧化锆(ZP)为TiO ₂的前驱体，通过溶胶-凝胶浸涂技术在玻璃基板上制备TiO ₂ -ZrO ₂复合涂层和 ZrO ₂，然后分别在 500 ^o下煅烧C/1 小时。样品通过 FTIR、拉曼、紫外/可见光/近红外、GIXRD、FESEM、TEM 和 XPS 研究进行表征。涂层的厚度和 RI 是用椭圆光度法测量的。发现涂层厚度为 110±10 nm、折射率为 1.95±0.05 的镀膜玻璃均匀，具有良好的硬度 (≥3H) 和粘附性能。FTIR 和 XPS 分析证实了 Ti-O 和 Zr-O 的键合性质，而拉曼和 GIXRD 研究揭示了 TiO ₂ -ZrO ₂复合材料的结晶性质。FESEM 和 TEM 图像分别显示沉积涂层的无裂纹和蜘蛛网状性质。包覆TiO ₂ -ZrO ₂复合材料在 350-2500 nm 的波长范围内显示 >20% 的平均反射。上述纳米复合镀膜玻璃可用作高效节能建筑构件的热反射窗。
