Abstract

Aerogel granules or micropowders are suitable matrixes for the incorporation of hybrid molecules with promising optical or electrical applications. By using a two-step colloidal preparation scheme red or green emitting complexes, [Eu(phen)₂(NO₃)₃] or [Tb(phen)₂(NO₃)₃] are immobilized in silica aerogel granules, leading to a bright red or green luminescence upon 350 nm excitation. The optical properties of SiO₂:Tb(phen)₂(NO₃)₃ composites are investigated depending on the preparation strategy. The quantum yield of the as prepared hybrid complexes and composites is discussed.
