METHOD OF LASER DEPOSITION OF NANOPARTICLES FROM SOLUTIONS Russian patent published in 2011 - IPC B81C1/00 B82B1/00 

FIELD: nanotechnologies.

SUBSTANCE: invention relates to the field of electrical engineering and nanotechnology, in particular, to production of electronic engineering and quantum electronics materials using technology of localised application of metal layers or nanostructures on surfaces of various types to produce elements and devices. The method of laser deposition of nanoparticles from solutions onto a substrate consists in its placement into a solution or application of a solution onto its surface. At the same time deposition is carried out from a colloid solution that consists of liquid, viscous phase (glycerine) and metal nanoparticles (for instance, Ni, Cu, Ti) and/or their oxides (NiO, CuO, TiO₂), capacity of laser radiation is varied in the range from the threshold capacity that makes 1-1.5 W to 4 W, laser radiation is focused at the side of the solution at the interface of substrate and solution, and radiation is scanned along the above specified surface with various speed.

EFFECT: development of a method of laser deposition of nanoparticles from colloid solutions, production of single or double component colloid solutions and nanostructured deposits at various substrates (dielectric, conducting, ceramic ones, etc) with the help of laser radiation.
