Characterization of an Active Matrix Binder Photoreceptor X-Form Metal-Free Phthalocyanine in Poly(N-vinyl Carbazole)

Abstract

The photoconductivity of a binder‐type photoreceptor, the X form of metal‐free phthalocyanine in poly(N‐vinyl carbazole) is shown to involve: a field‐assisted thermal carrier dissociation step; an exclusive hole injection across a field‐lowered barrier, i.e., Schottky emission; and facile hole transport across PVK layers. Highly efficient photoresponse peaks in the near infrared indicate that the lowest triplet state is an intermediate in the generation of charge carriers in the X form of metal‐free phthalocyanine.
