Abstract
Spatial inhomogeneous distributions of the electroluminescence radiation density are studied in ac driven thin film ZnS:Mn electroluminescent (ACTFEL) devices. Apart from stationary microfilaments, dynamical patterns occur on a timescale ranging from tenths of a second to several seconds. In particular, moving filaments and strings, fluctuating networks of strings, autowaves, or global oscillations may arise. The spatiotemporal structures are extremely sensitive to the conditions of preparation and the driving parameters of the samples.
