The Influence of Chromophores on the Magnitude of Space-Charge Fields in Photorefractive Polymeric Composites
Keyword(s):
This paper reports on the characterization of three poly(N-vinylcarbazole) (PVK)-based photorefractive composites with different non-linear optical (NLO) chromophores at an operating wavelength of 632.8 nm. The strength of the photoconductivity and the magnitude of the space-charge field (E SC) in the photorefractive composites are strongly affected by the chromophore’s highest occupied molecular orbital (HOMO). The magnitude of E SC increased with the lowering of the HOMO level of the NLO chromophores in the PVK composites.
