XANES and XEOL investigations of SiC microcrystals and SiC nanowires

Journal of Physics: Conference Series, 2009
X-ray absorption near-edge structures (XANES) at Si and C K-edge as well as X-ray excited optical luminescence (XEOL) have been used to investigate the electronic structures and optical properties of SiC microcrystals (SiCmcs) and SiC nanowires (SiCnws). SiCnws synthesized via thermal evaporation, have a SiC (β-phase)-core-SiO2-shell morphology.

Mechanism of X-ray excited optical luminescence in NaGdF4-based nanoparticles

Results in Physics
X-ray irradiating rare-earth nanoparticles could emit fluorescence (∼50 keV) and luminescence (∼eV) photons simultaneously. Utilizing this phenomenon, it is expected to achieve online multi-modal imaging and integrated radiation and photodynamic therapy ...
