On the analogy between photoluminescence and carrier-type reversal in Bi- and Pb-doped glasses
Abstract
Reaction order in Bi-doped oxide glasses depends on the opticalbasicity of the glass host. Red and NIR photoluminescence (PL) bandsresult from Bi2+ and Bin clusters, respectively. Very similar centers arepresent in Bi- and Pb-doped oxide and chalcogenide glasses. Bi-implantedand Bi melt-doped chalcogenide glasses display new PL bands, indicatingthat new Bi centers are formed. Bi-related PL bands have been observed inglasses with very similar compositions to those in which carrier-typereversal has been observed, indicating that these phenomena are related tothe same Bi centers, which we suggest are interstitial Bi2+ and Bi clusters.
