Abstract

Er³⁺,Tm³⁺-codoped NaY(WO₄)₂ crystal was prepared by using Czochralski (CZ) pulling method. Absorption spectra, emission spectra and excitation spectra of this crystal were measured at room temperature. Such optical parameters as intensity parameters, spontaneous emission probabilities, branch ratios and lifetimes are calculated from absorption spectra with Judd-Ofelt theory. Transition processes of the energy levels of Er³⁺, Tm³⁺ are analyzed in details and the cross-relaxations: ¹G₄(Tm³⁺) + ⁴I_15/2(Er³⁺) → ³F₂(Tm³⁺) + ⁴I_13/2(Er³⁺). ¹G₄(Tm³⁺) + ⁴I_15/2(Er³⁺) → ³F₄(Tm³⁺) + ⁴F_9/2(Er³⁺) and ³H₄(Tm³⁺) + ⁴I_9/2(Er³⁺) → ³F₄(Tm³⁺) + ⁴S_3/2(Er³⁺) or ²H_11/2 between the two ions are put forward. Through the experiments, we have found that, in this crystal, Tm³⁺ strengthens luminescence of Er³⁺ in the green and red regions evidently. The above energy transfer processes provide potential applications of Tm³⁺ in Er³⁺-doped laser materials.
