Abstract :
The effect of different host polymers, PVK and PEMA on the performance of single-layer polymer-organic light emitting diodes (P-OLEDs) were investigated. The turn on voltage were measured about 6.5 volts and 7.5 volts for P-OLEDs involve PEMA and PVK respectively, while they had Imax values about 2.81 mA and 4.08 mA, during the test. The photoluminescence(PL) and also electroluminescence(EL) spectra of the samples were also investigated and compared with each other. While the PL spectra were stood in blue region, the EL spectra were covered indigo region. The spectra investigations show that the FWHM of samples involve PVK was larger than that of PEMA.
