The upconversion luminescence in Nd 3+ ‐doped bismuth–borate glass, excited by 0.8 µm 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.
