FIELD: chemistry.
SUBSTANCE: invention relates to luminescent materials, namely, to luminescent silver halide light guides designed as an advanced active medium in the manufacture of fibre lasers of the near and medium infrared ranges. Luminescent silver halide light guide contains silver halide ceramics of the composition AgCl0.2Br0.8, alloyed with oxides of rare earth elements, with the following ratio of ingredients, % wt.: AgCl0.2Br0.8 97.0 to 99.0; oxide of a rare earth element 3.0 to 1.0.
EFFECT: ensured generation during pumping in the near and medium IR spectral regions at room temperature.
