Internal charge-phosphor field characteristics of alternating-current thin-film electroluminescent devices

Abstract
The internal charge versus phosphor field (QFp) technique is proposed as a method for characterization of the electrical properties of alternating‐current thin‐film electroluminescent (ACTFEL) devices. QFp analysis provides direct information about the internal behavior of the ACTFEL device. The steady‐state field and internal conduction, polarization, leakage, and relaxation charges may be readily deduced from a QFp plot.
