Abstract

MoO3 clusters-coated TiO2 nanotubes were synthesized wet-chemically and characterized by measuring photoluminescence spectra and kinetic profiles as well as extinction spectra and electron microscope images. TiO2 nanotubes having an average outer diameter of 30 nm and an average thickness of 8 nm are surrounded by MoO3 clusters with an average thickness of 4 nm. The excitation of both the TiO2 cores and the MoO3 shells of the type-II nanocomposites suspended in water yields charge-transferred junction photoluminescence having a long lifetime of 2.3 ns at 460 nm.
