Abstract: The experimental results on transmission properties of linearly polarized light in TiO2 nanoclusters at room temperature are reported. It was found that the transmission change as increasing wavelength nonlinearly varied. The measured value for band-gap wavelength is about 396nm and it is less than that for bulk crystals. The result is in conformity with the blue-shift phenomena given by the quantum-size effect.
