A Stretchable Alternating Current Electroluminescent Fiber
Flexible, stretchable electroluminescent fibers are of significance to meet the escalating requirements of increasing complexity and multifunctionality of smart electronics. We report a stretchable alternating current electroluminescent (ACEL) fiber by a low-cost and all solution-processed scalable process. The ACEL fiber provides high stretchability, decent light-emitting performance, with exc...
متن کاملMonte Carlo simulation of electron transport in alternating-current thin-film electroluminescent devices
An ensemble Monte Carlo simulation of electron transport in bulk ZnS at different electric fields is presented. Scattering mechanisms associated with polar optical phonons, acoustic phonons (through deformation potential coupling), intervalley scattering, and impurities (neutral and ionized), are included in a nonparabolic multivalley model. Simulation indicates that the polar optical phonon an...
متن کاملStatic space charge in evaporated ZnS:Mn alternating-current thin-film electroluminescent devices
The operation of alternating-current thin-film electroluminescent ~ACTFEL! devices may be strongly affected by the presence of dynamic or static positive space charge within the phosphor layer during device operation. Dynamic space charge is a positive charge in the phosphor layer which is periodically created and annihilated during each period of the applied voltage waveform. In contrast, stat...
متن کاملHot-electron impact excitation of ZnS:Tb alternating-current thin-film electroluminescent devices
A new method of performing hot-electron impact excitation experiments using alternating-current thin-film electroluminescent (ACTFEL) devices is reported. This method relies on the use of a field-control circuit to control the magnitude of the phosphor field and consists of plotting the intensity of a given electroluminescence transition, normalized by the amount of conduction charge which flow...
متن کاملTransferred charge analysis of evaporated ZnS:Mn alternating-current thin-film electroluminescent devices
Evaporated ZnS:Mn alternating-current thin-film electroluminescent ~ACTFEL! devices are assessed via frequencyand temperature-dependent transferred charge analysis. The frequency-dependent trends involve the threshold voltage and the slope of the transferred charge immediately above threshold, both of which increase with increasing frequency. At ;15–20 V above threshold, the slope of the transf...
