Raman and X-ray Photoelectron Spectroscopy

Click For Summary
SUMMARY

This discussion focuses on utilizing Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) to analyze the effects of zinc (Zn) ions on the surface morphology of zinc-doped hydroxyapatite (HAp) coatings. The user seeks guidance on interpreting spectral data from Raman and XPS to identify changes in the coating due to Zn ions. Key recommendations include comparing spectra from clean Zn and coated samples, identifying new peaks, and analyzing peak shifts to understand the impact of Zn ions on the coating.

PREREQUISITES
  • Understanding of Raman spectroscopy principles
  • Familiarity with X-ray photoelectron spectroscopy (XPS) techniques
  • Knowledge of surface morphology analysis
  • Experience with spectral data interpretation
NEXT STEPS
  • Research how to interpret Raman spectroscopy spectra for peak identification
  • Learn about X-ray photoelectron spectroscopy (XPS) data analysis techniques
  • Study the effects of doping on hydroxyapatite coatings
  • Explore software tools for spectral analysis and peak identification
USEFUL FOR

Researchers, graduate students, and materials scientists focusing on surface analysis, particularly those investigating the effects of ion doping in coatings using Raman and XPS techniques.

How can I know the effects of ions on my coating using Raman and XPS?
Summary: How can I know the effects of ions on my coating using Raman and XPS?

Hi!
So I'm working on my thesis regarding surface morphology of Zn doped HAp coating. Now, my goal is to know the effects of Zn ions on the surface morphology of my coating using raman and xps. Jowever, I do not have any idea as to how I can possibly do this. I am really desperate to find answers, please help. I have zero background on this and I can't seem to find academic articles that can help me out.

Er... why can't you do Raman and XPS on CLEAN Zn first, then coat the surface, and then do Raman and XPS once again? Compare the two results and see what's different.

Uhmm, yes, that process is done. However, that's where my problem comes, I don't know how to use the results to know the effects of my ions on the coating.

This is vague.

1. Do you see differences in the spectra?

2. More importantly, do you see extra peaks in the spectra that weren't there for the clean Zn surface?

3. Don't you have charts or software that can make identification of those peaks?

4. Do you see shifts in the original Zn peaks?

5. What in the world is your thesis advisor doing that you can't seek help from him/her?
