摘要
用Bridgman-Stockbarger方法在Ar气氛下生长了Eu^(2+):KMgF_3晶体。测量了该晶体的紫外吸收光谱,激发光谱和荧光光谱。用氮分子激光器激发该晶体得到的高分辨荧光光谱显示了多中心结构。
Perovskite type single crystals of Eu^- ion doped KMgF_3 have been grown by the Bridgma-Stockbarger technique in Ar atmosphere, Absorption, emission and excitation spectra of the crystal are presented and discussed. High resolution fluorescenee spectrum obtained for the crystal pumped with N_2laser shows that the crystal is many center structure.
