DEPENDENCE OF LITHIUM FLUORIDE COLOR CENTER AGGREGATION EFFICIENCY ON CATION AND ANION IMPURITY DISTRIBUTION
The regularities of impurity effect on the formation efficiency, aggregation and variety of color centers in LiF crystals are studied. It is shown that specially introduced impurities contribute to the formation of the color centers with new spectral characteristics due to radiation exposure. It is found out that distribution of cation and anion impurities determined by the features of crystal growth increases the formation efficiency of radiation point defects in tens and more times by making crystals less radiation-resistant.
