| Abstract: | Various sizes of nanometer CdS were prepared in AOT/isooctane/water reverse micelles. Eosin and Rose Bengal were chosed as probes of CdS,and photoinduced charge interactions between CdS and the above xanthene dyes were studied. The results of irradition experiments and ESR techniques revealed the interaction mechanism of these dyes injecting their excited electron to the valance band of CdS. |
