HYBRID NANOCOMPOSITE MATERIAL, LASER SCANNING SYSTEM AND USE THEREOF FOR VOLUMETRIC PROJECTION OF IMAGE Russian patent published in 2020 - IPC G03B21/606 H04N5/74 B82Y20/00 

FIELD: physics.

SUBSTANCE: present invention relates, in fact, to hybrid nanocomposite materials used for volumetric projection, for example, when creating 3D image (for example, in the entertainment industry or in medicine). Hybrid projection matrix comprises a synergetic combination of particles of two different types. First type of particles consists of nano-emitting particles which are capable of nonlinear absorption of one or two photons and visible light radiation. Second type of particles consists of an additive which improves nonlinear absorption of one or two photons and emits visible light with nano-emitting particles. Said one or more additives is selected from the following group: gold nanoparticles, silver nanoparticles, semiconductor nanoparticles, nanocellulose, carbon nanotubes, two-dimensional materials, graphene and conductive and/or semiconductor polymers.

EFFECT: technical result is improved spatial effect of projection and reduced required laser power.
