We report on the design, manufacturing and testing of Alq3/polyvinylcarbazole (PVK) light emitting devices. The devices were obtained by spin coating PVK films on indium tin oxide coated glass substrates. Alq3 films were then deposited by high vacuum thermal evaporation. The devices were topped by depositing magnesium/silver electrodes by thermal evaporation. After deposition, the samples were stored and operated under a nitrogen atmosphere in order to prevent damage due to oxidation. The thickness of the active layers was purposely chosen to be large in order to study the device with an electro-optic reflectometric technique.

Abstract
We report on the design, manufacturing and testing of Alq3/polyvinylcarbazole (PVK) light emitting devices. The devices were obtained by spin coating PVK films on indium tin oxide coated glass substrates. Alq3 films were then deposited by high vacuum thermal evaporation. The devices were topped by depositing magnesium/silver electrodes by thermal evaporation. After deposition, the samples were stored and operated under a nitrogen atmosphere in order to prevent damage due to oxidation. The thickness of the active layers was purposely chosen to be large in order to study the device with an electro-optic reflectometric technique.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
