Local properties of impurity and defects investigated by high pressure spectroscopy

Abstract

Using the high-pressure spectroscopy, the pressure shifts of the luminescence related to the d-d transitions in transition metal ions and d-f transitions in rare earth ones, which interact with the nearest neighbor host ions of dielectrics, are investigated. The results are obtained for Ti³⁺, Ce³⁺, Pr³⁺, and Cr³⁺ ions in various lattices.
