Abstract
An organic–inorganic quantum well embedded on porous anodic alumina was synthesized and studied by MEB, AFM, optical absorption and photoluminescence. The morphology determined by the MEB and the AFM, shows that the size of the pores is about 10nm for alumina evaporated on glass substrate and about 35nm for alumina template prepared in sulfuric acid (H2SO4). The optical properties are characterized from absorption and photoluminescence spectra measured at room and low temperature. The measured spectral characteristics demonstrate the influence of the pore size on the emission of the organic–inorganic quantum well ((C12H25NH3)2PbI4). An obvious blueshifted photoluminescence (PL) of (C12H25NH3)2PbI4 in nanometer-sized pores was observed. It results in a better quantum confinement.
