Materials Design of Organic Lasers Aimed at Low Lasing Threshold

Abstract

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