NaCl(OH-)中K+对F+2型心的形成及其光谱性质的影响
Effects of K+Ion on Formation and Optical Properties of +2-Like Color Centers in NaCl(OH-)
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Pollock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 Na1-xKxCl()H-) crystal as a laser medium.
