Abstract : Research and development work on polycrystalline CdSe photoconductors for (eventual) switching of large electroluminescent displays is described. A powder sintering procedure, followed by either a spray or a settling technique for depositing the powder onto the substrate, was used to fabricate the photoconductor cells. The settling technique was found to be more reproducible, easier to control and less costly than the spray method. Various pertinent processing variables were studied including the amount of dopant and fluxing agent added, the sintering temperature and time, the concentration of oxygen in the sintering ambient and the particle size. A number of measurements were made in order to fully characterize the photoconductors, clarify the role of various processing variables and understand the many aspects of the photoconductive processes.
