Abstract
Organic semiconductor lasers are immature due to material constraints. The development of high-performance organic gain media is key to enhancing device performance. Here, a new organic laser material based on carbazole-end-capped bis-stilbene (AD-BSBCz) is reported. It has excellent thermal stability and electrical properties, low amplified spontaneous radiation threshold (0.86 μJ/cm2), and good solubility for solution deposition. High-quality amorphous thin films of AD-BSBCz are easy to prepare by vapor deposition. A simplified OLED device using AD-BSBCz as the light-emitting layer can emit blue light up to 25,000 cd/m2 with an external quantum efficiency of 1.99 %, demonstrating the excellent electroluminescence performance of AD-BSBCz.
