Zusammenfassung: 
The upconversion luminescence in Nd3+-doped bismuthborate glass, excited by 0.8 mu m light, was studied in the visible spectral region. Four distinct emission bands were found. From their kinetics, two mechanisms can be shown to be responsible for all four lines: energy-transfer upconversion, slightly dominating, and excited state absorption.
