NaCl晶体中氧族离子稳定的(F+2)H心

描述了掺氧族离子（Ｏ＾２－，Ｓ＾２－，Ｓｅ＾２－）ＮａＣｌ晶体中（Ｆ２＾＋）Ｈ心的制备过程，报道了氧族离子稳定的（Ｆ２＾＋）Ｈ心的吸收光谱和发射光谱，测量了这些（Ｆ２＾＋）Ｈ心的室温避光稳定性。研究表明，氧族离子对Ｆ２＾＋心的稳定作用顺序为Ｏ＾２－〈Ｓｅ＾２－〈Ｓ＾２－，而受这三种离子扰动的（Ｆ２＾＋）Ｈ心的光谱峰位相对于纯Ｆ２＾＋心的移动大小亦为这一顺序。这一顺序与它们相应元素的电子亲合能顺序相

Chalcogenide Ions Stabilized(F2+)H-Like Color Centers in NaCl Crystal

The preparation procedures of(F2+)H centers in chalcogenide ions doped NaCl crystals are described,absorption and emission spectra are studied. The stability of these centers in the dark at room temperature is also mearsured.It is revealed that the increase of the stabilized effect of chalcogenide ions on F2+ centers is in the sequence of ions O2-,Se2-,S2-and that the increase of the shift magnitude of spectral positions based on these defects comparing with pure F2+ center is in the same sequence. The sequence is the same as the electron affinity sequence,While the electron affinity of the chalcogenide elements is 1.47,2.02,2.07eV,respectively.It is also experimentally found that with increase of the chalcogenide ion size,the growth of good quality doped crystal is achieved more difficultly.
