Luminescence Properties of Eu2+-Doped Glass Ceramics Containing SrF2 Nanocrystals

Résumé

The Eu2+-doped glasses and glass ceramics containing SrF2 nanocrystals were prepared and their luminescence properties were investigated. The formation of SrF2 nanocrystals in glass ceramics was confirmed by X-ray diffraction and transmission electron microscopy. The melting in a reducing atmosphere and then the crystallization of glass resulted in the reduction of almost all Eu3+ ions to Eu2+ ions in the glass ceramics. The Eu2+-doped glass ceramics containing SrF2 nanocrystals exhibited a much stronger broad blue emission band and a longer lifetime of excited state than the glasses.
