Abstract

$Y_2SiO_5:Ce$ phosphor was coated with $In_2O_3$, $Al_2O_3$ and $SiO_2$ and then their cathodoluminance(CL)proper-ties required in field emission display were investigated. It was found that luminance efficiency and aging p개perty of $Y_2SiO_5:Ce$ phosphor was decreased with $In_2O_3$coating. For the case of coating, the luminance intensity was in blue phosphor was dramatically increased with $SiO_2$ coating. And also the aging property of $Y_2SiO_5:Ce$ Phosphor coated with $SiO_2$ was significantly improved compared to non-coated sample.

$Y_2SiO_5:Ce$ 형광체를 $In_2O_3$, $Al_2O_3$ 및 $SiO_2$로 코팅한 후 전계 방출 디스플레이에 요구되는 음극선 발광 특성을 조사하였다. $Al_2O_3$ 코팅으로 $Y_2$SiO(sub)5:Ce 형광체의 발광 효율과 에이징 특성은 감소되었다. 한편 $Al_2$$O_3$코팅으로 형광체의 발광효율은 증가하였으나 발광스펙트럼과 색좌표는 일부 변화하였다. 그러나 $Y_2SiO_5:Ce$ 청색 형과체의 발광 효율은 $SiO_2$코팅으로 크게 증가하였으며, 또한 $SiO_2$ 코팅한 $Y_2SiO_5:Ce$ 형광체의 에이징 특성은 코팅 전에 비하여 크게 향상되었다.
