Abstract

산소영향을 받지 않고, 전자선 여기에 의해 발광하고, 원료물질의 선택에 따라 각종 발광색을 실현할 수 있고, 휘도특성 및 수명특성이 우수한 형광체를 제공한다.
Ga2S3을 23.5g과, MgCl2를 0.04(Mg로 0.2몰%)을 혼합하여 석영보드에 석영보드에 얹고, 석영관안에서 유량 10ml/min으로 암모니아를 유입하면서 1100℃ 온도하게 10시간 유지하면, GaN:Mg형광체가 얻어진다. MgCl2의양을 0.001몰%∼10몰% 범위로 변화시켜서 복수종류의 시료를 얻어진다. 각 형광체 시료를 이용하여 형광표시판을 작성한다. 각 시료의Mg의 몰%와, 전자선의 사돌에 의해 발광할 때의 휘도의 상대강도 관계를 나타낸다. Zn 또는 Mg의 가장 바람직한 범위는 0.001∼0.3이고, 이 범위에서 발광강도의 상대치는 피크시의 약 70% 이상이 된다.
