FIELD: terahertz elements. SUBSTANCE: invention relates to a new terahertz (THz) element base for the range of 0.1-10.0 THz, namely, optical halide nanocrystalline ceramics of the TlCl0.74Br0.26 - AgI system, designed to transmit terahertz and infrared radiation. Ceramics is in demand for applications in optics, photonics, laser and nuclear technology in the visible, infrared, and terahertz ranges. Terahertz nanocrystalline ceramics is made on the basis of a solid solution of monovalent thallium chloride-bromide composition TlCl0.74Br0.26 and additionally contains silver iodide, in the following ratio, mol.%: solid solution TlCl0.74Br0.26 66-96; silver iodide 34-4. EFFECT: obtaining a nanocrystalline ceramic material for the production by extrusion of a new class of flexible nanocrystalline light guides resistant to UV and radiation. 1 cl, 3 dwg, 3 ex.
