Abstract: The invention relates essentially to the field of hybrid nanocomposite materials for uses in volumetric projection, for example such as in 3D imaging (such as the field of entertainment or the medical field). In particular, the invention describes a binary hybrid projection matrix, including at least two types of (nano)particles and/or different molecules (quantum dots, metal nanoparticles; carbon nanotubes), a method for manufacturing the matrix and a 3D projection system and method that includes the use of the matrix. The addition of the second type of particles makes it possible to modify the properties of the matrix in order to achieve better volumetric projection performance or else to generate new features that did not exist with a single particle. The new matrix also makes it possible to reduce the power of the laser used for the projection while obtaining equivalent brightness to that of existing matrices.

Abstract: The detection method can include: exciting at least one fluorescent microsphere floating in said solution under test by exposing it to excitation light; measuring a fluorescence spectrum of said at least one fluorescent microsphere, said fluorescence spectrum comprising multiple whispering gallery modes; obtaining a set of predetermined fluorescence spectra corresponding to those of microspheres having varying external refractive index and varying radius, identifying a matching fluorescence spectrum of the set which more closely matches the measured fluorescence spectrum; comparing the matching fluorescence spectrum of the set to the measured fluorescence spectrum.
