Abstract
Materials with strong infared optical properties are of great technological importance for a wide range of applications that include optical communication,medical imaging,astronomy,and remote monitoring of industrial equipment and the environment.Typical infared materials include intrinsic and extrinsic semiconductors,quantum wells,superlattices,organic dyes,and thermal detectors such as thermopiles,bolometers,or pyroeletric devices. For infared detection applications,semiconductors such as HgCdTe, PbS, and GeInAs efficiently collect radiation across the infared spectrum. However, for many optical filtration and biomedical applications, there is a requirement that the infared material be incorporated into another media, that it be nontoxic, or that the material be small enough to pass through a specific pore size.
In this study, we use silica nano crystals as the infared material. We messured the infared transmission property of them that were separate on silicon substrate to reseach what happened on the infared transmission property of the samples.As the same way, we also messured the infared transmission property of the samples that the silica nano particals were separate on gold gratings that were destruct on silicon substrate.
