Abstract
The luminescence spectra of BaTiO3 and SrTiO3 at small grain sizes and room temperature reveal an apparent single-emission band at 596 and 5 72 nm respectively. The visible emission band is found to increase in intensity and its peak position is shifted to larger energy as the gra in size decreases. The properties of photoluminescence versus grain si ze are investigated for the first time.
