Abstract :
Nanohybrid solution and thin film of Rhodamine 6G (R6G) or pseudo-isocyanine (PIC) with the titanate nanosheets (HTO) of H1.07Ti1.73O4·nH2O with a lepidocrocite-like layered structure were fabricated by using a soft chemical process. The optical properties of the nanohybrids were investigated by absorption and fluorescence spectroscopies. An H-aggregate of the R6G molecules was formed in the R6G–HTO nanohybrid system, while a J-aggregate of the PIC molecules was formed in the nanohybrid PIC–HTO system. Fluorescence quenching behavior was observed in both of the R6G–HTO and PIC–HTO nanohybrid systems.
