N2 - We successfully grew bulk single crystals of VOx and TiOx with a sodium-chloride structure by the floating-zone method, and we performed optical reflectivity measurement and pump-probe spectroscopy to clarify the electronic structure of these series of compounds and their x dependence. We found that optical spectra can be discussed on the basis of the Mott-Hubbard model, although a disorder arising from the deficiencies of Vi or Ti and O plays an important role in the electronic structure as well as their x dependence.
