Abstract

original image

A simple, two-phase approach using an autoclave is taken to synthesize high-quality anatase TiO2 nanocrystals with a narrow size distribution (see Figure). The size-tunable luminescence of the TiO2 nanocrystals is dominated by band-edge luminescence at room temperature. The nanocrystals could be readily dispersed in toluene after capping with stearic or oleic acid.
