Optical, Thermo-Mechanical and Acoustic Properties of Organic-Inorganic [(CH₂OH)₃CNH₃)]H₂PO₄ Crystals

Abstract

The results of studies for the refractive indices dispersion, optical activity, electro- and piezooptic effects, electrogyration effect, thermal expansion and ultrasonic wave velocities in organic-inorganic [(CH ₂ OH) ₃ CNH ₃ )]H ₂ PO ₄ crystals are presented. The coefficients describing those effects are determined. It is found that [(CH ₂ OH) ₃ CNH ₃ )]H ₂ PO ₄ crystals are characterized by a high electrooptic figure of merit.
