Abstract

본 발명은 고연색 3파장형 형광램프에 사용되는 녹색발광 형광체에 관한 것으로서, 하기의 일반식으로 표기되는 것을 특징으로 하는 녹색발광형광체는 소성에 의한 휘도 열화와 램프 점등중 광속 유지율의 저하를 현저히 개선시킨 새로운 조성의 형광체이다.The present invention relates to a green light emitting phosphor used in a high color three-wavelength fluorescent lamp, characterized in that the green light emitting phosphor characterized by the following general formula significantly reduces the luminance deterioration by firing and the reduction of luminous flux retention during lamp lighting. It is an improved phosphor of a new composition.
