FTIR Studies of Silicon Carbide 1D-Nanostructures

2015

Stable 1D silicon carbide nanostructures (nanowires) have been obtained via combustion synthesis route. Infrared absorption and reflection spectra for as-obtained and purified SiC nanowires were compared with the spectra of commercially available SiC nanomaterials. Principal vibrational modes have been identified. Reflectivity spectrum has been reconstructed by modeling of the dielectric function

Synchrotron radiation studies on luminescence of Eu2+-doped LaCl3 microcrystals embedded in a NaCl matrix

2012

Abstract LaCl3:Eu2+ microcrystals dispersed in the NaCl matrix have been obtained in the NaCl–LaCl3(1 mol.%)–EuCl3(0.1 mol.%) crystalline system. The low-temperature luminescent properties of these microcrystals have been studied upon the VUV and UV excitation by the synchrotron radiation. The spectroscopic parameters as well as decay time constants of Eu2+-doped LaCl3 host have been established. The excitation mechanism of divalent europium centers through energy transfer and reabsorption is discussed.
