摘要
用自行研制的电注入装置,在693K温度下施加DC1200V电压、对溴化钾晶体进行电注入并使之有效着色。在着色溴化钾晶体中产生大量F,R,M,N类和一些新的未知色心,并给出色心形成和转化机理。对着色晶体进行系统光谱测量和分析,用解谱法将相应色心光谱带从测得光谱中合理地分解出来,并精确确定其光谱参数。
Potassium bromide crystals were effectively colored electrolytically with a lab-made electrolytic apparatus at 693 K by applying a DC 1200V voltage. A lot of F, R, M and N type and some new unknown color centers were produced in the colored potassium bromide crystals, and the formation and transformation mechanisms of the color centers were presented. Spectral measurement and analysis were carried out systematically for the colored crystals, the spectral bands of corresponding color centers were reasonably resolved from the measured spectra, and the corresponding spectral parameters of the spectral bands were accurately determined by using spectral decomposition.
