摘要：
The usual absorption and luminescence of the trivalent ytterbium ions stand in the 900-1100 nm range. Under 355 nm laser excitation in ytterbium doped LiNbO3:MgO we observed in addition a weak broad band emission 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 luminescence in divalent ytterbium doped fluorides.
