Intensely Photoluminescent Pseudo-Amorphous SiliconOxyCarboNitride Polymer–Ceramic Hybrids
Abstract:SilconOxyCarboNitrides (SiCNO), made from thermal treatments of highly cross-linked silicon, nitrogen, and oxygen containing polymers, exhibit intense luminescence that is broadly distributed over wavelengths of 500–800 nm. The intensity is sensitive to the composition, and especially to the heat-treatment temperature (THT) of these new materials. The absorbance increases, and thus the brightness of the emission dims, as THT rises. The phenomenology suggests the presence of two, spatially and energetically separated, molecular complexes: one that absorbs and another that produces photoluminescence. The SiCNO are an entirely new class of high-temperature materials that can be molecularly tailored for optical device applications.
