We present a comparative investigation of the morphological, structural, and optical properties of vertically aligned ZnO nanowires (NWs) before and after high energy argon ion (Ar(+)) milling. It is found that the outer regions of the as-grown sample change from crystalline to amorphous, and ZnO core-shell NWs with ZnO nanocrystals embedded are formed after Ar(+) milling. Optical properties of the ZnO NWs have been investigated systematically through power and temperature dependent…

Excitonic properties and near-infrared coherent random lasing in vertically aligned CdSe nanowires.
TLDR
CdSe is recognized as a promising light-harvesting material to be applied in optoelectronics because of its fundamental emission in the near-infrared (NIR) region, and biosensors operating in this region can avoid interference from biological media such as tissue autofl uorescence and scattering light, and thereby facilitate relatively interference-free sensing.
