Amplified Spontaneous Emission and Electroluminescence from Thiophene/Phenylene Co‐Oligomer‐Doped p‐bis(p‐Styrylstyryl)Benzene Crystals

Enhanced amplified spontaneous emission (ASE) properties are demonstrated in dye-doped organic solid-state crystals. Optically pumped ASE with a low threshold (3 μJ cm-2) is obtained from α,ω-di(biphenyl)-terthiophene (BP3T)-dopedp-bis(p-styrylstyryl)benzene crystals; ∼3 times lower than that of BP3T single crystals. The doped crystals show ambipolar charge-carrier transport, resulting in bright electroluminescence from the crystal edge under electrical pumping.
