Opti cal and structural studying o f Molybdenum-dop ed Vanad ium oxid e by sol-gel method

Transition-metal oxides attra ct a large a mount of attention beca use of their large vari ety of physic al and chem ical properties. Vanadi um oxide thin films were identified as useful cathode materials for lithi um-ion batt eries due to its high capacity, high voltage and low cost. Sol-gel nano film may be appropriate because of its advantages such as high purity, simplicity of equip ment and scalability. W e report a facile synthesis of nano structured Vanadium oxide films by using Vanadium pentoxide and Ammoniu m heptamol ybdate tetrahydrate pow ders. The aim of this work is to present a structural and optical study on Molybdenum doped Vanad ium oxide thin films pr epared by sol-gel dip coating rout. Structural, optical properties and m olecular vib ration modes were characterized by X-ray diffraction (X RD), UV-Visible, and F ourier transform infrared (FTIR) spectroscopy.
