制备了一种有机电致发光（EL）二极管与酞菁染料和二萘嵌苯颜料之间的高增益有机光响应异质结相结合的多层器件。红光照射下的EL输出被可逆地擦除叠加蓝光照射，由于在有机/有机异质结的光电流倍增现象的光抑制。图像转换的空间分辨率被确认为小于280 µm。本函数可被视为光学“非”操作。
A multilayered device combining an organic electroluminescent (EL) diode with a high-gain organic photoresponsive heterojunction between phthalocyanine and perylene pigments was fabricated. The EL output under red light irradiation was reversibly erased by superimposing blue light irradiation, due to the photo-suppression of the photocurrent multiplication phenomenon at the organic/organic heterojunction. The spatial resolution for image conversion was confirmed to be finer than 280 µm. The present function can be regarded as an optical “NOT” operation.
