Raman and X-ray Photoelectron Spectroscopy

Click For Summary

Discussion Overview

The discussion revolves around the use of Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) to analyze the effects of zinc ions on the surface morphology of zinc-doped hydroxyapatite (HAp) coatings. Participants explore methods for interpreting spectroscopic results to understand the influence of these ions on the coating.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks guidance on how to determine the effects of Zn ions on their coating using Raman and XPS, expressing a lack of background knowledge and difficulty finding relevant academic resources.
  • Another participant suggests performing Raman and XPS on clean Zn before and after applying the coating to compare results and identify differences.
  • A follow-up response questions the original poster's ability to interpret the results, asking if they observe differences in spectra, extra peaks, or shifts in original Zn peaks, and whether they have access to software for peak identification.
  • Concerns are raised about the original poster's reliance on their thesis advisor for assistance in this process.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to interpret the spectroscopic results, and the discussion remains unresolved regarding the specific methods for analyzing the data.

Contextual Notes

There are limitations regarding the original poster's background knowledge and the specific details of their experimental setup, which may affect their ability to analyze the results effectively.

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?
