Abstract

Synthesized solid solutions of (Y_1-x-y-zYb_xEr_yHo_z)₃Al₅O₁₂, studied their luminescence characteristics, the dependence of the intensity of the Stokes IR luminescence band 0,96-1.1 microns and 144-1.68 microns, 1,83-2,15 microns, the concentration of ions, Yb³⁺, Er³⁺, Ho³⁺, when excited by laser radiation with a wavelength of 0,94 microns. The analysis of the obtained relationships and determined the optimal composition of the phosphor (Y_0,85-xYb_0,1Er_0,05Ho_x)₃Al₅O₁₂, for maximum energy conversion efficiency from the near-infrared region at 2100 nm.
