| Abstract: | Light emitting diodes(LED) based on polymeric thin layer have attracted much interest and polymer LED emitting blue light is particularly desirable. In this paper, a newly dye and polymer complex teraphenylbutadiene (TPB ) doped Poly (N -vinylcarbazole) (PVK) as the emitter in electroluminescent device has been examined and the emission characteristics of the LED have been discussed. The electroluminescent diode consists of a thin polymer film sandwiched by indium/tin-oxide (ITO)and Al electrodes.Blue emission centered at 455 nm has been observed at room temperature. The maximum luminescent intensity of 44 cd/m2 at a bias less than 20 V and a current density of 50 mA/cm2 is achieved. |
