Abstract

We demonstrate the lasing properties of 4,4’-bis[(N-carbazole)styryl]biphenyl (BSBCz) thin films under electrical pumping. The device incorporates a mixed-order distributed feedback SiO2 grating in an organic light-emitting diode structure and emit blue lasing. The results provide an indication of lasing by direct injection of current into an organic thin film through selection of a high-gain organic semiconductor showing clear separation of the lasing wavelength from significant triplet and polaron absorption and design of a proper feedback structure to suppress losses at high current densities.
