초록
We report the electric properties of organic light emitting diodes (OLEDs) by controlling the carrier density according to the crystalline of copper(II) phthalocyanine(CuPc) and the irradiation light intensity. OLEDs were constructed with indium tin oxaide (ITO)/CuPc/triphenyl-diamin (TPD)/tris-(8-hydroxyquinoline)aluminum (Alq3)/Al. The transport properties of OLEDs were changedby the heat-treatments of CuPc. The irradiation of red and blue light exciting CuPc, TPD and Alq3. And then we observed the carrier density of OLEDs.
