A LIGHT EMITTING DIODE AND A FABRICATION METHOD THEREOF, AND A METHOD FOR IMPROVING THE LIGHT-EMITTING EFFICIENCY THEREOF USING POLYMER BLEND

摘要

The present invention provides a light emitting diode having excellent luminous efficiency, which is used as a light emitting layer by mixing (blending) a long polyconjugated light emitting polymer and a light emitting polymer having a constant conjugation length at a predetermined ratio because the conjugate length is not controlled, and a method of manufacturing the same. And it relates to a method of improving the luminous efficiency of the light emitting diode.;The method of improving the luminous efficiency of a light emitting diode according to the present invention includes a process of mixing (blending) a conjugated light emitting polymer and two or more light emitting polymers having a constant conjugated length in a predetermined ratio and using the same as a light emitting layer of the light emitting diode. In the light emitting diode comprising a light emitting diode of the present invention, a substrate, an anode wave disposed on the substrate, a light emitting layer located on the anode, and a cathode located on the light emitting layer, the light emitting polymer having a conjugated light emitting polymer and a constant conjugated length A polymer-polymer blend prepared by blending two or more kinds is used as a light emitting layer of a light emitting diode. The method of manufacturing a light emitting diode according to the present invention includes a light having a constant conjugated length and a conjugated light emitting polymer on the anode. Made of a polymer-polymer blend prepared by blending two or more light emitting polymers with Characterized in that it comprises the step of forming a thin film.
