Abstract
The usual absorption and luminescence of the trivalent ytterbium ions stand in the 900-1100 nm range. Under 355 nm laser excitation in ytter bium doped LiNbO3:MgO we observed in addition a weak broad band emissi on extending from 700 to at least 900 nm. Its lifetime is about 1 mu s . Its excitation spectrum is composed of at least one band near 325 nm . This unexpected luminescence has similarities with well-known lumine scence in divalent ytterbium doped fluorides.
