Abstract

Time-integrated and picosecond time-resolved excitonic luminescence of cation-substituted Zn_xCd_1-xS (0 xS_1-x system) versus binding by impurities. Tunneling in the range x xS_1-x. It is suggested that in cation-substituted Zn_xCd_1-xS the broadened levels of impurity-bound excitons are involved in tunneling whereas the contribution from the disorder-induced fluctuations of crystal potential is less important than in anion-substituted CdSe_xS_1-x.
