Electrical Characterization of Thin-film Electroluminescent Devices
Electrical characterization methods for the analysis of alternating current thinfilm electroluminescent (ACTFEL) devices are reviewed. Particular emphasis is devoted to electrical characterization techniques because ACTFEL devices are electro-optic display devices whose performance is to a large extent determined by their electrical properties. A systematic procedure for ACTFEL electrical asses...
متن کاملOperation of GaN : Er Thin Film Electroluminescent Display Devices
Thin-film electroluminescence has been obtained from GaN:Er deposited directly on amorphous dielectric layers. Electroluminescent device (ELD) structures consisting of a dielectric/GaN/dielectric were formed on p-Si substrates. In contrast to previous GaN:Er ELDs which used epitaxial growth conditions on crystalline substrates and were operated under DC bias, these ELDs were operated under AC b...
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 کاملAlkali metal coactivators in SrS: Cu,F thin-film electroluminescent devices
A unique approach for obtaining bright and efficient saturated green phosphors for alternating-current thin-film electroluminescent ~ACTFEL! device applications is presented. The approach involves color-shifting blue SrS:Cu,F ACTFEL phosphors into the green region of the spectrum via the incorporation of alkali metal ions into the SrS lattice. Alkali metals are incorporated into SrS:Cu,F phosph...
متن کاملThin-film solid-state electroluminescent devices based on tris(2,2'-bipyridine)ruthenium(II) complexes.
The behavior of light-emitting electrochemical cells (LEC) based on solid films ( approximately 100 nm) of tris(2,2'-bipyridine)ruthenium(II) between an ITO anode and a Ga-In cathode was investigated. The response times were strongly influenced by the nature of the counterion: small anions (BF(4)(-) and ClO(4)(-)) led to relatively fast transients, while large anions (PF(6)(-), AsF(6)(-)) produ...
