Abstract

The ESEEM spectroscopy was used to determine positions of the ¹⁴³Nd³⁺ impurity ions in Y₂SiO₅ single crystal. It is established that neodymium ions substitute yttrium ions in the Y2 positions with seven nearest oxygen ions. Crystal field parameters of ¹⁴³Nd³⁺ impurity centers in isotopically pure Y₂²⁸SiO₅ and Sc₂²⁸SiO₅ single crystals were determined using data of CW EPR spectroscopy and the known energy level schemes.

Keywords: Crystal field parameters; EPR; ESEEM; Orthosilicate crystals.
