Abstract

본 발명은 형광 램프 제조용 적색 발광 형광 조성물에 관한 것으로서, Y2O3을 모체로 하고 Eu2O3를 부활제로 하고 융제로서 AlF3을 형광조성물 전체에 대하여 0.5 내지 3중량% 포함되도록 한 것으로서 시간의 경과에 따른 광속의 감소량이 적은 적색 발광 형광체를 제공한다.The present invention relates to a red light-emitting fluorescent composition for the manufacture of fluorescent lamps, comprising Y 2 O 3 as a parent, Eu 2 O 3 as an activator and AlF 3 as a flux to contain 0.5 to 3% by weight of the entire fluorescent composition. Provided is a red light-emitting phosphor with a small amount of reduction in the luminous flux with elapsed time.
