Abstract
An organic light emitting diode (OLED) utilizes dysprosium incorporated tris-(8-hydroxyquinoline) aluminum (Alq3-Dy) as the emissive layer. The OLED, which can be fabricated as a multi-layer device with each layer having a thickness of 30-300 nm, provides a luminance value at a voltage ranging from 24V to 30V of 3000-15000 cd/m. In comparison to similar OLEDs which utilize pure Alq3, the diodes with the Alq3-Dy layer provide an electroluminescence intensity 20 times higher than diodes with a pure Alq3 layer (Alq3 OLED). In addition, the peak position (EL emission band) of the Alq3-Dy OLED is shifted to the higher wavelength side by 10 nm compared to that of the pure Alq3 OLED (from 515 nm to 525 nm).
