Abstract

Abstract We report on light refraction by titania particles with a high refractive index (approximately 2.4). Clusters of titania particles modified using a fluorescent dye, rhodamine B isothiocyanate, and nonfluorescent titania particles were prepared. When the clusters were irradiated using light at the excitation wavelength of the fluorescent dye, the edges of the bound nonfluorescent particles glowed brightly. Geometric optics and finite difference time domain calculations revealed that this phenomenon was due to a lens effect caused by titania particles.
