Abstract

A well-known red fluorescent dye 4-(dicy-anomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) was codoped with an electron transport organic molecule tris(8-hydroxyquinoline) aluminum (Alq3) in a host matrix of polystyrene (PS), and the amplified spontaneous emission (ASE) was studied by optically pumping. It was found that the ASE performance was significantly improved by the introduction of Alq3. The Alq3:DCJTB:PS blending thin films showed a low threshold (2.4μJ/pulse) and a high net gain coefficient (109.95cm1) compared with the pure DCJTB:PS system (threshold of 15.2μJ/pulse and gain of 35.94cm1). The improvement of the ASE performance was considered to be attributable to the effective Föster energy transfer from Alq3 to DCJTB. Our results demonstrate that the Alq3:DCJTB could be a promising candidate as gain medium for red organic diode lasers.
