| dc.description.abstract | Reaction order in Bi-doped oxide glasses depends on the optical basicity of the glass host. Red and NIR photoluminescence (PL) bands result from Bi2+ and Bi-n clusters, respectively. Very similar centers are present in Bi- and Pb-doped oxide and chalcogenide glasses. Bi-implanted and Bi melt-doped chalcogenide glasses display new PL bands, indicating that new Bi centers are formed. Bi-related PL bands have been observed in glasses with very similar compositions to those in which carrier-type reversal has been observed, indicating that these phenomena are related to the same Bi centers, which we suggest are interstitial Bi2+ and Bi clusters.

| dc.description.abstract-translated | Koncentrace Bi v oxidových sklech závisí na optické bazicitě hostitele. Chalkogenidová skla se chovají velice podobně, měřením fotoluminesce jsme zjistili, že Bi se v těchto sklech vyskytuje v nové entitě podobné té, ktérá stojí za změnou typu vodivosti (nositelů proudu) pozorované dříve u těchto materiálů. | cze |
