Abstract
Light absorption in TiO2 nanoparticles is analyzed. The interface mechanism of light absorption, where the indirect interband electron transitions are caused by the possibility of the momentum nonconservation at the interface , is considered. This mechanism is found to be most important for crystalli tes, which are generally a few 10 nm or less in size.
