| 摘 要： | 研究了Ｋ＋对ＮａＣｌ（ＯＨ－）中（Ｆ＋２）Ｈ心的形成及其光谱性质的影响。结果表明，Ｋ＋的存在抑制了Ｆ＋２型心的形成，改变了（Ｆ＋２）Ｈ心的光谱性质，拓宽了发射谱的半功率谱宽。从而修正了Ｐｏｌｏｃｋ的实验结果。同时指出，研制具有更宽波长发射范围的Ｎａ１－ｘＫｘＣｌ（ＯＨ－）复合基质Ｆ＋２型色心激光材料是可能的

| Abstract: | The effects of K + ion on F + 2 like color center formation and opical properties in OH - doped NaCl crystal are studied. The experiments show that K + ion suppresses the formation of F + 2 like centers and makes their absorption and emmission spectra broaden and red shift. With more dopants, the effect is stronger. The results suggested a correction on those given by C.R.Pollock group. As the FWHM of emission is increasing with K + dopants, it is possible to prepare F + 2 like centers in complex host Na 1-x K x Cl (OH -) crystal as a laser medium. |
