Bright Blue Emission From a New Species of Polymer Diode
-
Abstract
Blue emitting electroluminescent diode using PVCz doped with perylene and BBOT as electron transport has been constructed. The emission spectrum is a mixture of spectra of BBOT and perylene. A luminance of as high as 680cd/m2 with lumen efficiency more then 0.0281m/W have been obtained. -
