In this study, CdSe QDs were chemically adsorbed onto the inverse opal TiO 2 film as well as the common nanocrystalline TiO 2 film. The optical absorption studied by using photoacoustic (PA) spectroscopy implies the growing and larger amount of CdSe QDs onto inverse opal TiO 2 by increasing depositi
