摘　　要：在10K和室温条件下,对γ射线辐照着色NaCl晶体经光热处理后色心的光谱特性进行了系统研究。用解谱方法,将F2和F+3色心吸收峰从M吸收带中有效地分解出来,并精确地确定了其光谱参数。Spectral properties of color centers in colored NaCl crystals irradiated by y-rays at room temperature and treated optically and thermally were investigated systematically at 10 K and room temperature. Absorption peaks of F2 and F3+ color centers can be resolved efficiently from M absorption band in the crystals, and their spectral parameters were determined accurately by using spectral decomposition.
