KBr:Tl, luminescence and excitation spectra, low-dimensional KBr-TlBr system
Luminescence and excitation spectra of the systems on the basis of the nanoporous glass impregnated with KBr-TlBr and TlBr solutions as well as KBr single crystals surface-doped with thallium were studied in visible and ultraviolet regions at T = 77 K. It was shown that each of the studied systems has its peculiar optical properties, which differ from those of the corresponding macroscopic single crystals. The results are discussed taking into account the physicochemical features of the thallium insertion in the preparation of samples from solutions.
