TERAHERTZ-INFRARED CONVERTER FOR VISUALIZATION OF SOURCES OF TERAHERTZ RADIATION Russian patent published in 2018 - IPC G02F2/02 G01J5/08 B82B1/00 

FIELD: physics.

SUBSTANCE: converter consists of a base and transducers of terahertz radiation into infrared radiation. The base is made in the form of a matrix, transparent in the terahertz and infrared ranges of frequencies. Transducers are evenly distributed in the volume of the matrix and are made in the form of gold nanoparticles. The diameter of gold nanoparticles is determined by the formula D≈[(8/π)⋅(m_Au/ρ)⋅(E_F/hν)]^1/3, where D is a diameter of gold nanoparticles, m_Au - a mass of the gold atom, ρ - a density of gold, E_F - Fermi energy of gold, hν - a photon energy of terahertz radiation.

EFFECT: increasing the conversion efficiency and sensitivity of the device.
