Summary
The Institute of Physics offers consumers solid-state substrates for giant Raman scattering using silvered porous silicon based on a manufacturing agreement and is looking for partners to to conclude an distribution services agreement.
Description
A technique has been developed for the preparation of solid-state substrates for giant Raman scattering (GRS) based on silvered porous silicon (PC). Correlations have been established between the morphological parameters of the initial PS substrates and the GRS activity of silver nanostructures. The obtained substrates have a high GRS signal amplification factor (2x108), surface homogeneity, and retain their sensitivity during long-term storage in air (up to 1 month). The possibility of detecting picomolar concentrations of a substance using silver-plated PS substrates has been demonstrated.
Advantages and Innovations
GRS-active nanomaterials will significantly increase the sensitivity of optical sensor devices using the GRS effect and can be used for highly sensitive detection and study of trace amounts of complex organic compounds (harmful emissions, drugs), heavy metals, etc. correspond to the world level. The cost of the developed substrates is 5..7 US dollars, which is 2..3 times less than the cost of analogues.

Additional comments
The Institute of Physics of the National Academy of Sciences of Belarus has scientific contacts with most developed countries. Currently, more than 50 agreements on scientific and technical cooperation have been concluded with organizations from 15 countries.

The Institute of Physics conducts research within the framework of international projects of the HORIZON 2020 program. One of the projects in which employees of the institute participate is SUPERTWIN (Ultra-high resolution microscopy on entangled states of photons), which includes 8 centers from Italy, Switzerland, Germany, France, Netherlands and Belarus. In the course of the ACTRIS-2 project (Aerosol, Cloud and Trace Gas Research), an annual cycle of measurements of altitude profiles of atmospheric aerosol parameters was carried out. The measurement results are presented to the database of the European lidar network EARLINET.

The Institute of Physics develops, manufactures and supplies to many countries of the world (Russia, China, Germany, France, USA, Saudi Arabia, India, etc.) laser and optical devices for various purposes, as well as innovative components for laser technology.
