Abstract:: The experimental results on transmission spectrum in metal ion doped TiO₂ nanoclusters at room temperature are reported. It is found that the transmission in the metal ion doped TiO₂ nanoclusters are decreased significantly. The transmission change as increasing wavelength nonlinearly varied and there is a maximum in the transmission change curve in metal ion doped TiO₂ nanoclusters.
Key words:: metal ion dopants; TiO₂ nanoclusters; transmission
