摘要：

Excitonic electroabsorption (EA) of CdxZn1-xS (x = 1.0, 0.8, 0.7 and 0.0) solid solution single crystals was investigated at 150 and 77 K. The EA spectra have been analysed within the context of the Stark theory that enables the lowest bound exciton states in the solid solution at each composition to be located precisely. This allows the determination of the reduced effective mass of the exciton which is found to vary linearly with the optical band gap a.s predicted theoretically.
