Guanylurea(1+)hydrogen phosphite: a novel promising phase-matchable material for second harmonic generation

Abstract

A novel and promising material, guanylurea(1+) hydrogen phosphite, which belongs to the group of inorganic salts of polarizable organic molecules was prepared. Its real potential for optical applications is based on the simplicity of synthesis, good ability to crystallize, transparency, thermal stability and efficiency of the second harmonic generation comparable to urea.
