Y. Wang et al., Preparation and characterization of nanoscopic organic semiconductor of oxovanadium phthalocyanine, J COLL I SC, 213(1), 1999, pp. 270-272
Nanoscopic particles of oxovanadium phthalocyanine (VOPc, phase-II) with di
fferent particle sizes are prepared by aggregation of VOPc molecules in the
presence of surfactants for the first time. A size effect in the region of
nanoscale was observed in the UV-visible spectra. The photoconductivity of
the nanoscopic VOPc is much higher than that of bulk VOPc. (C) 1999 Academ
