Light-emitting electrochemical cells (LEECs) have been drawn attention for possessing easy-to-fabricate and energy efficient light-emitting characteristics. In this work, we have investigated the electrical properties of LEECs based on transition metal complex, which is PEDOT:PSS-incorporated tris(2,2'-bipyridyl) ruthenium(II) hexafluorophosphate. Performance characteristics include carrier mobility, current density-voltage, light intensity-voltage, response time and turn-on voltages. The devices were fabricated as a sandwiched structure and light-emitting layer was deposited approximately 60nm thickness by spin coating. Relationship between the contents of the conjugated polymer in the luminous layer and electrical properties of device was investigated. Electrical properties were measured using optical spectrometer, and morphology changes of the luminous layer were observed using XRD and AFM. |
