Abstract

Absorption bands in the wave-number range of 3525-3470 cm^-1 have been observed in K_1-yLi_yTa_1-xNb_xO₃ (KLTN) doped crystals except in crystals doped with Cu and V. These absorption bands are attributed to the O-H vibration band. The hydrogen concentration in KLTN doped crystal is controllable either by doping or by heat treatment. The activation energy of hydrogen ion migration is between 0.6 and 0.7 eV in KLTN doped crystals. The [H ⁺] ion is identified as responsible for fixing (screening) the holographically produced electronic grating.
