Ionic conductor based alternating current electroluminescent device
Alternating current electroluminescent (AC-EL) devices have been explored for many years. Comparing the advantages of AC-EL to DC operated devices, there are still limitations to overcome before bringing it to commercial level application.

| Summary: | Alternating current electroluminescent (AC-EL) devices have been explored for many years. Comparing the advantages of AC-EL to DC operated devices, there are still limitations to overcome before bringing it to commercial level application.
In this project, lithium perchlorate (LiClO4) is used as the ionic salt for the conductive electrode and silicon rubber Ecoflex 00-50 with zinc sulfide (ZnS) powder embedded as the phosphor layer. This project studies the conditions for curing the ionic conductor layer, effect of Poly(methyl methacrylate) (PMMA) molecular weight on device performance, variation of component(s) concentration forming ionic conductor gel and addition of barium titanate (BaTiO3, BTO) in the phosphor layer. A luminescence device with the phosphor layer sandwiched between ionic conductor layer is performed. |
