Near-IR System for Nanophotonics

Nanophotonics is one of the most exciting new fields to come out of nanotechnology. The quantum-confinement effects observed in these very small (~10 nm) particles can lead to unique optical properties. Rare-earth (RE) doped materials are particularly of interest due to their fluorescence emissions in the visible and infrared regions of the spectrum. There is an interest in examining the effects of particle size on the fluorescence properties of RE-doped nanopowders, for the optical characteristics of RE ions are strongly influenced by their local bonding. Because most photonic devices require these powders be incorporated into a host matrix (i.e., polymer, glass, solvent), there is a need to investigate the emission properties in different host materials. A fully-integrated HORIBA Scientific spectroscopy system (sample chamber, TRIAX550 monochromator, detectors) was employed to study the effects of different solvents on RE-doped nanopowders
