Abstract

The fabrication of that consist of multiwalled boron nitride nanotubes (BNNT) and organic π-electron donors was investigated. A charge separation between the ZnPc moiety and the BNNT during illumination was disclosed by optical spectroscopy techniques. The quenching of ZnPc emission within a broad 640-800 nm band was observed after adding BNNT. The time-resolved fluorescence was further investigated by using a streak scope, by which a similar red-shift in the emission peak was observed as in steady-state fluorescence spectra. An obvious decay in fluorescence was also found due to the ultrafast dc-excitation process in a 2/BNNT hybrid in water. The transient absorption spectra were measured to obtain information on the excited states directly after the nanosecond laser light excitation of ZnPc/BNNT hybrids. Fluorescence spectroscopies revealed electronic transfer in these hybrids.
