Description

음극선관용 형광체
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 종래의 장잔광(長殘光) 형광체(Zn,Mg,Mn)3(Po4)3의 자극중의 발광강도를 100으로 하였을 때의 상대휘도를 고려한 도면, 제3도는 이 발명의 형광체에 있어서, BaF2의 함유량에 의한 잔광시간의 변화를 표시한 도면

Claims (2)

  1. 일반식 Y2O2S : Eu로 표시되는 3가 유로품으로 부활시킨 산유화이트륨에 불화바륨을 함유시킨 것을 소성시켜서 되는 음극선관용 형광체.
  2. 청구범위 제1항에 있어서, 상기 불화바륨의 함유량은 0.1∼5.0중량%인 것을 특징으로 하는 음극선관용 형광체.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
