Abstract :
Photoluminescence (PL) and photoluminescence excitation (PLE) measurements on View the MathML source asymmetric coupled double quantum wells were performed to investigate the hot-exciton luminescence phenomena. The PLE spectra indicated the creation of hot excitons and subsequent relaxation by longitudinal optical-phonon emission resulting from the localization of excitons due to fluctuation of the CdxZn1−xTe alloy well.
