100% fluorescence efficiency of 4,4′-bis[( N -carbazole)styryl]biphenyl in a solid film and the very low amplified spontaneous emission threshold

We examined the amplified spontaneous emission (ASE) characteristics of fluorescent styrylbenzene derivatives doped into a 4,4′-di(N-carbazolyl)biphenyl (CBP) host. In particular, 4,4′-bis[(N-carbazole)styryl]biphenyl (BSB-Cz) demonstrated an extremely low ASE threshold of Eth=0.32±0.05μJ∕cm2. We ob...
