Determination of Optimum Zn content in Cd1-xZnxS Nanoparticles

Sabit HOROZ, Arzu EKINCI, Omer SAHIN

Abstract


CdZnS NPs containing concentrations of 0.25, 0.5, 1, 3 and 5% Zn were synthesized at room temperature by chemical precipitation method and then incident photons to current efficiency (IPCE) measurements were performed to determine optimum Zn concentration in CdZnS NPs. Moreover, Zn2SnO4, a ternary compound semiconductor, was used instead of TiO2 as counter electrode for the first time. As a last part of the study, the structural and optical properties of CdZnS NPs containing optimum Zn content were investigated, respectively. Consequently, it appears that CdZnS NPs have a higher efficiency than CdS and that Zn doping play an important role in this increase.
