Abstract
The PL and EL chararacteristics 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 quorum efficiency. Dopingperylene and DCJTM in these BAlq was found to be useful in tuning the emission colors from blue to orange-red, including white, with improvements in the operational stability.
