Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...

A RIGOROUS COMPARISON OF METHODS FOR MULTI-WALLED CARBON NANOTUBES PURIFICATION USING RAMAN SPECTROSCOPY

Multi-walled carbon nanotubes (MWNT’s) were synthesized using chemical vapor deposition (CVD) method in a fluidized bed reactor under the flow of methane and hydrogen gases. A Cobalt-molybdenum/magnesium oxide (Co-Mo/MgO) nanocatalyst was used as the catalyst of the process. The samples were analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The effects of d...

A Novel Technique for Raman Analysis of Highly Radioactive Samples Using Any Standard Micro-Raman Spectrometer

A novel approach for the Raman measurement of nuclear materials is reported in this paper. It consists of the enclosure of the radioactive sample in a tight capsule that isolates the material from the atmosphere. The capsule can optionally be filled with a chosen gas pressurized up to 20 bars. The micro-Raman measurement is performed through an optical-grade quartz window. This technique permit...

Silica (agate-jasper) mineralization in the Chah Andoo plain, SW Damqan by Micro-Raman spectroscopy

The Chah Andoo plain is located about 100 km SW Damqan in Semnan Province. Basalt, andesite-basalt, tuff and metamorphic rocks are the main rocks which exposed in the study area. Agate, jasper and agate–jasper are silica minerals widespread at the plain surface as crushed fragments from a few millimeters to 0.5 meter in dimension. Banded (mono centric), stalactite (landscape), mossy and thunder...
