Abstract

Absorption and magnetic circular dichroism spectra of Tm³⁺ ions in LiNbO₃ crystal have been investigated at various temperatures between 15 and 296 K, and luminescence spectra observed by excitation in various excited states of Tm³⁺ have been investigated in a spectral region of 400-1750 nm at room temperature. From absorption spectrum at 15 K, it is confirmed that Tm³⁺ ion has C₃ symmetry, indicating that they occupy Li⁺ and/or Nb⁵⁺ sites. The 480, 652, 780, 800, 1220, 1450, and 1650 nm emission bands were observed by excitation into the ¹G₄ state and the 800, 1450, and 1650 nm emission bands were observed by the excitation into the ³F₂, ³F₃, and ³H₄ states, and the 1650 nm emission band was observed by excitation into the ³H₅ states. Their optical transition processes are discussed.
