Caracterização óptica de cristais de L-Treonina irradiados

Abstract

In this work we study the linear and nonlinear optical properties of the L-threonine amino acid crystal submitted to high-dose of X-ray energy, sufficient to cause damage to the molecules and change their originals properties. The choice of this amino acid is because the elements of their family present good results in applications for nonlinear optical devices. This amino acid was crystallized by the method of slow evaporation of the solvent and the method of slowly varying temperature. Measurements were carried out optical absorption, linear refractive index and nonlinear, comparing these properties with non-irradiated crystal.
