A novel electroluminescent device is constructed using organic materials as the emitting
elements. The diode has a double‐layer structure of organic thin films, prepared by vapor …

Electroluminescent (EL) devices are constructed using multilayer organic thin films. The
basic structure consists of a hole‐transport layer and a luminescent layer. The hole‐transport …

A thin-film, two-layer organic photovoltaic cell has been fabricated from copper phthalocyanine
and a perylene tetracarboxylic derivative. A power conversion efficiency of about 1% has …

Highly stable organic electroluminescent devices based on vapor‐deposited Alq thin films
have been achieved. The improvement in stability is derived from several factors including: (1) …
