Abstract

종래의 Y2SiO5:Tb 녹색발광 형광체의 모체 일부를 Pr으로 치환한 본 발명의 녹색발광 형체는 일반식 Y2-X-y Prx Tby SiO5(단 1x10-5≤x≤x5x10-3, 0.1≤y≤0.14)로 표시되는 것을 특징으로 하는데, 종래의 것에 비해 발광휘도가 높고 온도에 대한 안정성이 우수하여 고선명 텔레비젼(HD-TV)이나 투시관 용으로 적합한 녹색발광 형광체이다.The green light emitting body of the present invention in which a part of the mother of the conventional Y 2 SiO 5 : Tb green light emitting phosphor is substituted with Pr is represented by the general formula Y 2 -Xy Prx Tby SiO 5 (wherein 1x10 -5 ≤x≤x5x10 -3 , 0.1≤ y? 0.14), which is a green light-emitting phosphor suitable for high-definition television (HD-TV) or viewing tubes due to its high luminance and excellent stability to temperature compared to the conventional one.
