Organic bistable light-emitting devices (OBLEDs) with an aluminum (Al)-nanoparticle-embedded tris(8-hydroxyquinoline)aluminum (Alq₃) layer and double emitting layers (EMLs) were fabricated to investigate their color switching behaviors. Scanning electron microscopy images showed that Al nanoparticles were formed on the Alq₃ layer. The Al nanoparticles in the Alq₃ layer improved the storage margin of the organic bistable devices (OBDs), and the double EMLs changed the emission color of the organic light-emitting devices (OLEDs) according to the variations of the ON and the OFF states of the OBDs. The variations of the ON and the OFF states of the OBDs could be clearly distinguished by the color switching of the OLED. The luminances of the OBLEDs with double EMLs in the ON and the OFF states were 641.80 and 22.25 cd/m², respectively, and their CIE coordinates at 20 V were (0.42, 0.46) and (0.51, 0.47), respectively, which corresponded to the ON and the OFF states of the OBLEDs.

制备了具有铝（Al）-纳米粒子嵌入的三（8-羟基喹啉）铝（Alq ₃）层和双发射层（EML）的有机双稳态发光器件（OBLED），以研究它们的颜色切换行为。扫描电子显微镜图像显示Al纳米颗粒形成在Alq ₃层上。Alq _3中的Al纳米颗粒层提高了有机双稳态器件（OBD）的存储裕度，并且双EML根据OBD的ON和OFF状态的变化改变了有机发光器件（OLED）的发射颜色。通过OLED的颜色切换可以清楚地区分OBD的ON和OFF状态的变化。具有双EML的OBLED在ON和OFF状态下的亮度分别为641.80和22.25 cd / m ²，其在20 V时的CIE坐标分别为（0.42，0.46 ）和（0.51，0.47）到OBLED的ON和OFF状态。
