A Study of Excitonic Spectra in CdSxSe1−x Mixed Crystals

Abstract: Cathodoluminescence and reflectivity spectra are studied in homogeneous CdS,Sel --2 mixed crystals with x = 0.85, 0.64, 0.47, 0.29 over the temperature range 7 to 110 K. It is found that the luminescence at 7 K is dominated by bound exciton emission. The binding energies of exciton complexes are deduced from the spectra and found to decrease linearly with the increase of selenium content in the crystals. It is concluded that excitons in different CdS,Sel-mixed crystals are bound to the same impurity or defect.… Show more
