Spectroscopic characterization of optically active defect center containing diamond nanostructures

Abstract

Optically active defect centers or so called ―color centers‖ in nanocrystalline diamond (NCD) crystals are very promising nano-objects and they are attracted the interest of many researchers and companies in the last decades. These structures have unique physical and optical properties like intensive, stable and narrow emission band, single photon emission and optically addressable and readable spin state at room temperature. These properties in combination with the unique nature of diamond crystal contribute to the development of quantum information processing, nanophotonics, nanobiology and nanomedicine.
