Depth elemental characterization of 1D self-aligned TiO2 nanotubes using calibrated radio frequency glow discharge optical emission spectroscopy (GDOES)

Radio Frequency Glow Discharge Optical Emission Spectroscopy Depth Profiling Analysis of Thin Anodic Alumina Films as Potential Reference Materials

s in any form of chemical analysis, the quality of information obtained from a depth profiling experiment is only as good as the reference materials that are used to calibrate the instrument. In the case of depth profiling, calibration must take place in terms of chemical composition as well as distribution with respect to the specimen surface. The nature of applications requiring such analyses...

RF Glow Discharge Atomic Emission Spectroscopy of Non-Conducting Materials

Spatially resolved observation of a radio-frequency-powered glow discharge plasma for emission spectrometric analysis.

In glow discharge optical emission spectrometry, two-dimensional emission images for iron atomic lines were measured by using an imaging spectrograph equipped with a CCD detector, when a radio-frequency (r.f.) power source was employed for excitation. Emission images at the Fe I 371.99-nm and the Fe I 375.82-nm lines, having different excitation energies, were analyzed by the two-line method to...

Evaluation of Nitrogen Diffusion in Plasma Nitrided Iron by Various

   Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...

Optical Emission Spectroscopy of Diffuse Coplanar Surface Barrier Discharge

Diffuse coplanar surface barrier discharge (DCSBD) as the source of nonequilibrium plasma is widely used nowadays for surface modification of different materials. DCSBD plasma consists of many microdischarges which are moving along the planar dielectric plate and create a thin layer of macroscopically homogeneous plasma above dielectric. The influences of humidity in carrier gas at atmospheric ...
