Abstract

Colloid particles, composed of ZnO and ZnS particles in contact or ZnO colloid particles coated with ZnS, have been investigated. The effect of various amounts of ZnS on the ZnO visible emission was studied. The results show that ZnS quenches the ZnO visible emission by hole transfer; however, fast recombination between the electron and hole takes place at the ZnO-ZnS interface. This is reflected by a decrease in the yield of reduction of methyl viologen upon addition of ZnS to the ZnO-methyl viologen system.
