Nanosilicon is one of the most promising nanomat. having unique structural and optoel. properties that can be used in biomedicine,optoelectronics,sensing and nanothermometry.Its properties do not allow the creation of one luminescent multi-functional nanoplatform requiring merging of different nanomaterials.Temperature-sensitive silicon-based nanocomposites with tuned multi-band emission are demonstrated.One can easily achieve the change of their single- and multi-band photoluminescence spectral position from ∼1.6 eV to ∼2.9 eV by varying the experimental parameters.The “white” emission of silicon nitride is also observed that can be further applied for sensing or optoelectronic applications.The presence of silver nanoparticles leads to 80% increase of the temperature sensitivity of the photoluminescence maximum position (from ∼540 μeV/°C to ∼975 μeV/°C).The plasmonic nanostructures also considerably modify the ratiometric temperature behavior of nanocomposite emission.
