Paper Abstract

Organic materials, and in particular, poly(p-phenylene vinylene)s, are being investigated for solid state neutron detection. Semiconducting organics can offer direct detection because of high resistivity, high dielectric strength, natural gamma discrimination due to low Z, and room temperature operation. However, the effective charge collection is dependant on several material processing variables, including solvent choice and concentration, substrate, deposition method and conditions, post-deposition processing, and other factors, all of which can influence the local and bulk order of the material. We have investigated the effects of processing variables on the material order through infrared dichroism. The charge collection of the device was measured with visible laser excitation, and related to the order.
