摘要：
We studied influence of annealing in water vapour and proton exchange on high-pressure low-temperature luminescence spectra of near stoichiometric LN: Cr, MgO crystals, containing both Cr-Li and Cr-Nb centers by using diamond-anvil cell technique. The observed changes of the spectra of Cr3+ ions are associated with the larger inhomogeneous broadening and increase of the splitting of the 2 E level of the so called 6 CrNb center. This shows that neither increase of hydrogen concentration in LN by almost two orders of magnitude (from 10(18) to almost 10(20) cm(-3)) nor proton-exchange procedure do not create any new optically active Cr3+ centers in those crystals. This does not support the hypothesis about the close compensation of Cr-Nb(3+) sites in LiNbO3 crystals by hydrogen
