Abstract

The PL and EL characteristics of several blue Alq (BAlq) emitters and the effect of doping with blue and red fluorescent molecules have been studied. Substitution at the 2 and 4 positions was found to produce a substantial blue shift in the emission peak relative to the green Alq and a relatively large improvement in the fluorescence quantum efficiency. Doping perylene and DCJTM in these BAlq was found to be useful in tuning the emission colors form blue to orange-red, including white, with improvements in the operational stability.
