Materials Design of Organic Lasers Aimed at Low Lasing Threshold

As the next generation optoelectronic devices, i.e., post- organic light emitting diodes (OLEDs), semiconductor laser (OSLDs) are supposed to be fascinating devices due their unique properties such as a wide range of emission wavelength tunability, low-temperature fabrication allowing flexible and compatibility with present OLED technologies. In this report, by focusing on most promising material 4,4’-bis[(N-carbazole)styryl]biphenyl (BSBCz), materials design lasing molecules photophysical current injection device summarized.
