PHOTOREFRACTIVE MATERIAL AND BATH FOR MANUFACTURING THEREOF Russian patent published in 2009 - IPC C09K9/00 G03C1/725

Abstract RU 2346972 C1

FIELD: chemistry.

SUBSTANCE: invention relates to photorefractive material and may be used in optoelectronic devices, dynamical hologram recording and other photonic technologies. Mixed oxide of La_1-xSr_xYO_3-δ formula, where 0.1 ≤ x ≤ 0.27, is described as photorefractive material. Also, bath for production thereof is described. It contains yttrium oxide, strontium carbonate and lanthanium yttriate, ratio of components being as follows (wt %): LaYO₃ - 64.32-85.71; Y₂O₃- 4.76-23.79; SrCO₃ - remainder to 100.

EFFECT: higher photorefractive effect of material.
