Abstract

The photorefractive effect in a nominally undoped 0.91PbZn1/3Nb2/3O30.09PbTiO3 single crystal is measured. We report what is, to our knowledge, the first observation of the photorefractive effect in Pb-based relaxor ferroelectric crystals. The crystal is grown by the flux solution method. Then it is cut into a 2 mm×4 mm×8 mm piece and electrically poled along the [111] direction. The coupling constant of the two-wave mixing is 17 cm-1, and the normalized time constant under 1-W/cm2 illumination is 12 s at a wavelength of 476 nm. The effective trap density is calculated as 5×1016 cm-3 from the Debye screening length under the assumption of Kukhtarev’s band-transport model. The dominant carrier is identified to be holes from the direction of two-wave mixing energy transfer.
