Description

녹색발광 형광체Green light emitting phosphor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제3도는 본 발명의 형광체에 있어서 Cu 부활량이 0.005 중량부%인 경우의 Ce 함유량과 발광 휘도와의 관계를 나타낸 그래프이고, 제4도는 본 발명의 형광체에 있어서 Cu 부활량이 0.005 중량%인 경우의 Eu 함유량과 발광휘도와 과계를 나타낸 그래프이다.3 is a graph showing the relationship between Ce content and the luminescence brightness when the Cu activating amount is 0.005 parts by weight in the phosphor of the present invention, and FIG. 4 is the graph when the Cu activating amount is 0.005% by weight in the phosphor of the present invention. It is a graph showing Eu content, light emission luminance and transient.
