摘　　要：用自行研制的电注入装置,在不同条件下对氯化钠晶体进行电注入并使之有效着色。在着色晶体中有效地产生大量F、胶体C和N心,并研究了色心形成机理。对着色氯化钠晶体进行了系统光谱测量确定出这些色心的吸收光谱带光谱参数。通过计算得到氯化钠晶体F色心激活能为0.97 eV。Under different conditions,the sodium chloride crystals were colored with a homemade electrolysis apparatus.A lot of F,colloid C and N color centers were produced effectively in the colored crystals.The formation mechanism of the color centers was reserached.Systematic spectral measurements were carried out to the colored crystals.The parameters of the absorption spectral bands of the color centers were determined.The calculated value of the activation energy of the F color centers is 0.97 eV.
