초록

양자점 발광소자 기술은 지난 20여년 동안 급격한 발전이 이루어졌으며, 이는 양자점 발광체 및 소자기술 전반에 대한 집중적인 연구의 결과로 생각할 수 있다. 그러나 양자점 발광소자기술의 상용화를 위해서 해결해야 할 문제는 소재(예: 무중금속 양자점 구현, 대량생산 등) 및 소자(예: 수명문제, 대면적 프린팅문제, 효율저하문제)에 걸쳐 산적해 있다. 본 기고문에서는 이상의 다양한 문제 중 양자점 발광소자의 효율저하문제를 집중적으로 다루었다. 비록 양자점 나노구조체의 제어 및 발광소자 연구가 여전히 카드뮴 기반 양자점을 바탕으로 한 기초연구영역에 머물러 있지만, 향후 친환경 양자점 합성기술이 본격적으로 발전하게 된다면 우수한 효율과 안정성을 보이는 양자점 발광소자가 구현되리라 기대된다.
