In present study, sol-gel derived Ti_(1-x)Fe_xO₂(0 ≤ x ≤ 10%) rutile nanoparticles were synthesized and their structural, optical and morphological characteristics were studied in detail. XRD showed the single rutile phase of Ti_(1-x)Fe_xO₂ nanocrystals without impurity. FTIR and Raman spectroscopic analysis also confirmed the single phase lattice structure without any impurity detection. SEM images showed the spherical nanoparticle formation in samples. The optical energy band gaps were calculated from UV-Diffusion reflectance spectra (DRS) data and Urbach energy was estimated for prepared samples. PL analysis showed the presence of O vacancies and defects. The present study enhance the understanding of structural, morphological and optical properties of Ti_(1-x)Fe_xO₂ rutile nanocrystals for potential application in optoelectronics, photocatalytic activity, solar cells and ceramics.

在本研究中，合成了溶胶-凝胶衍生的Ti _（1-x） Fe _x O ₂（0≤x≤10％）金红石纳米颗粒，并详细研究了它们的结构，光学和形态特征。XRD显示Ti _（1-x） Fe _x O ₂为单金红石相无杂质的纳米晶体。FTIR和拉曼光谱分析也证实了单相晶格结构，没有任何杂质检测。SEM图像显示样品中球形纳米颗粒的形成。根据UV-漫反射光谱（DRS）数据计算光能带隙，并估算制备样品的Urbach能量。PL分析表明存在O空位和缺陷。本研究增强了Ti _（1-x） Fe _x O ₂金红石型纳米晶体的结构，形态和光学性质的理解，可用于光电子学，光催化活性，太阳能电池和陶瓷。
