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⁺.

铥和钬共激活倍半氧化钇陶瓷的光谱发光特性

本文介绍了由铥和钬共激活倍半氧化钇（Tm,Ho:Y2O3）制备的光学陶瓷的光谱和发光特性的研究结果。采用激光蒸发法制备了具有复杂化学成分的纳米级颗粒，采用固态真空烧结法制备了陶瓷样品。Tm，Ho:Y2O3陶瓷在2 μm区域的透光率超过82%，表明其具有良好的光学质量。在不同Tm3+/Ho3+比值的陶瓷中，Tm3+激发至3H4能级时，Tm3+的3F4→3H6跃迁和Ho3+的5I7→5I8跃迁的发光谱线强度的重新分布表明，Tm3+的3F4能级向Ho3+的5I7能级发生了非辐射能量传递过程。
