초록

$Y_2O_3$: Eu 형광체는 고효율, 열적 화학적 안정성을 갖고 있어서 평판 표시 소자용 적색 형광체로 널리 사용되고 있다. 고분해능과 고효율을 가지는 평판 표시 소자는 작은 크기의 구형 입자를 가진 형광체를 필요로 한다. 본 연구에서는 착체 중합법을 이용하여 100-300nm크기의 $Y_2O_3$ : Eu 형광체를 제조하였고 1족 혹은 2족 원소를 첨가하여 발광특성에 대한 영향을 검토하였다.

Europium activated yttrium oxide ($Y_2O_3$ : Eu) is extensively applied to red phosphor for Flat Panel Display because of its high efficiency and the thermal and chemical stability. Flat Panel Display screen which have a high resolution and high efficiency needs to the phosphors of ideally small size spherical particle. In this study, we prepared a $Y_2O_3$ : Eu phosphor using polymeric precursor methods and investigated the codoping effect by introducing the group 1 or 2 elements to $Y_2O_3$ : Eu phosphor in view of improvement of luminance efficiency.
