Abstract:

We review recent results form two types of small molecule organic light emitting devices (OLEDs). For flat panel display applications, we have
developed a novel OLED pixel in which the R, G and B emission layers are
vertically stacked to provide a simple fabrication process, minimum pixel
size, and maximum fill factor. In separate experiments, we have worked
towards achieving electrically- pumped organic lasers by demonstrating
low-threshold lasing in an optically-pumped thin film double
heterostructure consisting entirely of organic semiconducting materials.
