New Color Centers of the Short-Wave Range in Sodium and Lithium Fluorides
摘要
Abstract
The authors investigate the mechanism behind the formation of luminescence centers inside LiF crystals in the short-wave range (400–500 nm). The studied centers are found to be intrinsic crystal lattice defects, created by a radiation–thermal process. The proposed center model is obtained in the NaF lattice. It is established that new centers in sodium fluoride allow short-wave luminescence to be obtained in the yellow-green range.
