Raman imaging and spectroscopy of heterogeneous individual carbon nanotubes

Article Abstract:

An isolated singled-walled carbon nanotubes (CNTs) was investigated by atomic force (AFM) and confocal Raman microscopy with different excitation wavelength. Isolated carbon nanotubes are grown on substrates with patterned catalysts, by CVD methods and the characteristic pattern allows the study of same isolated tube with AFM and confocal Raman spectroscopy.

Optical spectra of a novel polyoxomtalate occluded within modified MCM-41

Article Abstract:

The novel polyoxometalate referred as Eu8P4W43 is immobilized inside the channels of MCM-41 mesoporous molecular sieve material by means of the incipient wetness method. A strong photoluminescence suggests the potential utility of the polyoxometalate as a luminescent material.

Polyoxoanion occluded within modified MCM-41: Spectroscopy and structure

Article Abstract:

The study was done on the Polyoxoanion occluded within modified MCM-41 by using spectroscopy. The results show that the anion is encapsulated with its long axis parallel to the pore axis and couples to the surface.
