Photopolarization characteristics of mercuric iodide binder layers

摘要

Photopolarization characteristics of mercuric iodide‐polystyrene layers have been investigated for use in photoelectret electrophotography. The highest charge density, which is a measure of photopolarization, is found to be of the order of 10-8 C/cm2 for 10% polystyrene in a mercuric iodide photoconductor. Considerations from electrophotographic applications show that a good image‐recording photoconductive layer is also obtained for 10% polystyrene in mercuric iodide.
