United for white: Bright white silica single layers are obtained by exploiting efficient red (Eu3+) and green (Tb3+) luminescent antenna complexes and a blue-light-emitting carbazole derivative (see picture). By combining the mild sol–gel solution route with the peculiar chemical and photophysical behaviour of selected light-emitting species, white luminescent materials with colour stability and shaped architecture are easily obtained through a molecular design strategy.
