Abstract

We report infrared (IR) measurements of protons (H+), present as OH−, in KTiOPO4 grown by various techniques. The IR spectra are sensitive to the growth technique used. In high temperature hydrothermally grown crystals we observe IR bands which have strongly temperature dependent linewidths. The Arrhenius-type activation energies for these linewidths are small (6–15 meV). The IR bands are polarized and this information can aid in making OH− site assignments.
