The resulting 1D nanostructures exhibit Ce3+-sensitized terbium(III) luminescence (green). Oxidation of Ce3+ results in an absence of energy transfer (ET) from Ce4+ to Tb3+ and thus no green emission of the sample (see picture). The effect can be reversed by reduction, thus giving a reversible luminescent switch.
