M. Yudasaka et al., DISORDERS AT INTERFACES - THIN-FILM JUNCTIONS OF NI PHTHALOCYANINE AND PERYLENETETRACARBOXYLIC DIANHYDRIDE FABRICATED BY VACUUM DEPOSITION, Thin solid films, 239(1), 1994, pp. 71-73
Ni phthalocyanine (NiPc) and 3,4,9,10-perylenetetracarboxylic dianhydr
ide (PTCDA) were deposited alternately on glass substrates under a pre
ssure of 2 x 10(-4) Pa. When PTCDA was deposited first followed by NiP
c, both materials were considered to diffuse mutually; this was deduce
d from X-ray diffraction analyses and optical absorption spectra. On t
he contrary, when NiPc was deposited first and followed by PTCDA, the
mixing of the two substances was not apparent.
