Complex ion centres in heavily doped NaBr: Tl phosphors

Published/Copyright: August 25, 2010

Abstract

The excitation and emission spectra of NaBr with high thallium content have been examined. The data obtained have revealed that the luminescence behaviour of heavily doped NaBr: Tl phosphor differs markedly from that of the lightly doped one. It has been shown that besides generally accepted isolated substitutional Tl+ ions, the charged complex ions of the type (TlBrn) also act as luminescence centres.
