Optical properties of nanomaterials
Literature data and the results of authors’ researches concerning the optical properties of nanomaterials are summarized in the review. We consider quantum size effects of nanoparticles in resonant-tunneling diodes, quantum-dot lasers and hypersensitive photodetectors. It was given an account of possible metal nanoparticles use as a new class labels in the study of biological processes in various tissues, due to the intensity of light scattering by nanometals that significantly exceed the brightest emission intensity of fluorescent molecules. In addition, the optical properties of fullerene C <sub>60 </sub>were considered, with their possible applications in medical practice.
