Optical Spectroscopy of Oxygen Vacancies in Rutile (TiO2) Irradiated with Argon Ions
摘要
Abstract
Single-crystal (001) rutile plate was irradiated intensively with 40 keV argon ions. Then, electromigration of oxygen vacancies was done in the irradiated rutile. The effect the concentration and charge state of oxygen vacancies has on the color, optical absorption spectra, and photoluminescence of rutile is shown.
