Characterization of Standard Reference Material 2943, Cu-ion-doped glass, spectral correction standard for blue fluorescence

► Fluorescence emission spectrum of SRM 2943 was determined for spectral correction. ► This Cu-ion-doped glass covers the fluorescence region from 380 to 560 nm. ► Fluorescence properties of the glass were determined, e.g., anisotropy and lifetime. ► SRM 2943 can replace the discontinued SRM 936a for many applications.
