Abstract

Results of investigating the spectral and luminescent characteristics of optical ceramics from thulium- and holmium- coactivated yttrium sesquioxide (Tm,Ho:Y₂O₃) are presented. The ceramic samples were fabricated using solid-state vacuum sintering of nano-sized particles with a complex chemical composition synthesized by laser evaporation. The transmittance of Tm,Ho:Y₂O₃ ceramics in the region of 2 μm exceeded 82%, indicative of their high optical quality. The redistribution of line intensities in the luminescence spectra of ³F₄ → ³H₆ transitions of Tm³⁺ and ⁵I₇ → ⁵I₈ transitions of Ho³⁺ observed upon excitation of Tm³⁺ to the ³H₄ level in ceramics with different Tm³⁺/Ho³⁺ ratios indicated the occurrence of a nonradiative energy transfer process from the ³F₄ level of Tm³⁺ to the ⁵I₇ level of Ho³⁺.
