| Popis: | UV-Vis absorption, photoluminescence (PL), and electroluminescence (EL) from heterostructure thin films made of 1,4-bis-(9-anthrylvinyl)-benzene (AVB) are investigated. UV-Vis absorption data are used to determine the band gap of the material which is estimated to be 2.28 eV. It is observed that the AVB electroluminescence spectrum is broad, ranging from 400 to 850 nm. The EL is obtained at a low voltage (less than 6 V) at which the current density is 3 mA/cm2. The current–voltage–electroluminescence (I–V–EL) characteristics are systematically studied in the ITO/AVB/Al device. The diode shows a power-law I–V dependence and a space-charge-limited current with traps (SCLC). |
