Abstract: 본 발명은 유기 발광 색소들이 아주 미량 도핑된 백색광을 내는 유기 고분자 발광 소재와 이를 발광층으로 사용하는 전기발광 소자에 관한 것으로, 유기 발광 색소들을 미량도핑하여 유기 발광 물질내에서 훼스터(Forster) 에너지 전달현상을 효과적으로 제어하여 고효율의 백색광을 내도록 하는 물질을 이용하여 백색 전기발광소자를 제조할 수 있다. 미량도핑법에 의한 백색 발광 물질 제조를 하게 되면 에너지 공여체인 호스트 물질과 에너지 수용체인 도판트 물질 사이에서는 에너지 전달을 이용할 수 있지만 도판트 사이에서의 에너지 전달은 효과적으로 차단할 수 있어 백색 물질 제조가 아주 용이하게 된다. 본 발명의 전지발광소자는 투명 기판, 반투명전극, 백색 발광층, 금속전극 순으로 구성되며, 경우에 따라서 정공 수송층과 전자 수송층이 더 포함될 수도 있다. 본 발명의 백색 발광 물질을 이용한 소자는 전기 발광(electroluminescence) 효율이 도핑하지 않은 단일 호스트 물질로 제조된 소자에 비하여 향상되었다.
