摘要
Sr_9Ca(PO_4)_6Cl_2:Eu^(2+)是一种性能良好效率较高的发光材料。作者合成并生长了Sr_9Ca(PO_4)_6Cl:Eu^(2+)的单晶体。从晶体的结构测定和光谱学研究,确证了晶体中存在有两种发光中心,即Eu(Ⅰ)中心和Eu(Ⅱ)中心。
Sr9Ca(PO4)6Cl2 :Eu2 + is a lamp phosphor with high efficiency . Its single crystals have been grown by programed cooling of flux. From the crystal structure determination and spectioscopic study, it has been found that there exist two luminescent centers in this crystal, namely Eu(Ⅰ) and Eu(Ⅱ).
