초록
현재 상용화되어 있는 PDP용 형광체의 물성에 있어서 청색 형광체는 열화, 색도변화, 휘도, 그리고 녹색 형광체는 잔광시간과 색순도, 적색 형광체의 경우에는 색순도에 대한 개선이 필요한 것으로 알려져 있다. 그 중 녹색 형광체로 Willemite 구조의 ZnSiO:Mn 형광체의 경우 발광효율은 우수하나 반면에 잔광시간이 길고 색순도(color purity)가 좋지 않다는 단점을 가지고 있다. 따라서 본 연구에서는 미세조정 조합화학기법을 이용하여 PDP에 적합한 새로운 고효율 형광체를 개발하였다. 화학적으로 정량인 가돌리늄 인산염(gadolinium phosphorous) 대신 인산을 과잉으로 첨가하여 탐색한 다음 과잉인산(excess phosphorous) 첨가 조성을 유지한 채로 가돌리늄(gadolinium)의 일정분율을 이트륨(yttrium)으로 치환하였다. 그 결과 최적 형광체 조성은 (G
