A. Brenier et al., LUMINESCENCE OF YTTERBIUM DOPED LINBO3-MGO UNDER UV EXCITATION, Radiation effects and defects in solids, 135(1-4), 1995, pp. 575-578
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.
