Abstract

We dried emitting layer of EL device at 30, 80, I20 and $150^{\circ}C$ for Ihr to investigate the effects to the emission characteristics of devices. PL intensity of P3HT thin film decreased with increasing the drying temperature. But, the EL intensity and stability of device with emitting layer dried at $150^{\circ}C$ were the best. We think it s because of absence of water and remaining solvent in P3HT emitting layer. So, We suggest that the drying temperature of emitting layer of EL device should be select slightly low temperature than its glass transition temperature.
