Abstract
The optical transition energy in zinc selenide (ZnSe)/tris(8- hydroxyquinoline) aluminum (Alq3) /N,N'-Bis(3-methyphenyl)-N,N -diphenylbenzidine inorganic-organic hybrid quantum well-like nanostructures (hybrid QW-like nanostructure) with well thickness of Aq3 from 10 to 50 nm were investigated by modulation spectroscopy as electroreflectance (ER) measurements. ER features due to optical transition energy were observed in the hybrid QW of well thickness. The transition energies were determined by fitting the ER spectra to the theoretical line-shape expression. The subband transition energy decreased with increasing well thickness might be due to the increase of well results in the reduction of quantum confinement energy. © 2007 IEEE.
