In this video tutorial, we will explore how to analyze UV-Vis absorbance data to obtain important information about nanoparticle size, morphology, concentration, and distribution. We will use OriginLab software to plot and analyze the data and obtain meaningful insights that can aid in research and development of nanoparticles.
We will start by importing the UV-Vis absorbance data into OriginLab and then proceed to plot and analyze the data using various tools and techniques available in the software. We will cover topics such as baseline correction, peak fitting, and curve smoothing to enhance the accuracy of our analysis.
This video is suitable for anyone interested in data analysis, particularly in the field of nanoparticle research. Whether you are a student, researcher, or scientist, this video will provide you with valuable insights on how to analyze and interpret UV-Vis absorbance data.

Hello, thank you for posting such a detailed method. The code is not giving me a best fit for my dataset, would you be able to help me work through the fitting parameters?
Thanks for the appreciation dear 😊.
Yes, sure. You may contact at sayphysics@gmail.com.
Good afternoon. Thank you for the very detailed video. I downloaded the folder but I don't have the program for the codes. Could you please tell me which one I should use? Thank you.
Thanks for the appreciation dear Carolina. The program in which the code is running is Mathematica. In case you would like me to do it for your data, we can discuss that.
Hi, thanks for the informative videos. Can we estimate/guess, maybe even qualitatively, the particle size from absorption spectra by only using Origin? Or any other simple method that does not involve Mathematica code as I don't have those codes
Thanks for the appreciation 😊.
I have provided the code as well as all the relevant files in the video description. However, for only estimation of the NPs sizes, you may watch my this tutorial. Thanks

sir what is the equation which gives relationship between nanoparticle size and wavelength using mie's theory
Please watch this video for it. Thanks

Hi, Thank you for sharing. Is it possible to use this code for nanorods as well or it is just for spherical? because I ran it for my samples which are nanorods and I did not get a good fitting
Yes, you're right. It's good for spherical and spheroidal NPs. We're working on it to include other morphologies like nanorods, nancubes, and nanoflowers etc. Thanks
@@SAYPhysics Thank you so much.
@aminrashidi1581 You're welcome dear
I have tried this method but for some reason in some spectra it works perfectly and others it doesn't, and it marks 1-RSS= infinity, therefore everything else comes out with errors. What can I do in this cases?
If it is working perfectly for some spectra, then it means there's no issue with the tutorial but with your some spectra. I'll suggest, you recheck your spectra and different values involved there. Thanks
is this method only for metal nanoparticle?can we apply it on nonmetal nanoparticles?
You may approximate the results in light of the literature, however, this method is for metal NPs. Thanks
Excuse me sir, how can i calculate the concentration in the unit of mg/mL or mol/L by using Mie fitting method. Thankyou
I don't know of any such calculations using Mie fitting. However, one can calculate it using UV-Vis data. The following video will help you how to do it. Thanks

In which way you ordered the UV-Vis data in Origin, ascending or descending?
Whether ascending or descending, plot in OriginLab remains the same. Thanks
However here in the fitting, it is to be in reverse order and with the same spacing (wavelength) as the dielectric constant spacing. Thanks
sir kindly upload videos about MATLAB basics.....
I'm sorry dear I'm not an expert in Matlab. Thanks
Salam Sir, Kindly upload tutorials about python (like C++) usage in physics.
I'm sorry. I'm not an expert in it. Thanks
Sir how about the intensity distribution and polarization distribution of nanoparticles in an optical potential well?
I will highly appreciate it, If you can guide us about it. thank you.
Using Rayleigh scattering approximation or Mie scattering approach. (image space and Fourier space).
Although I'm not that expert in this specific phenomenon and it's equally hard to explain it here in a comment, as detailed explanation is required. I will suggest to go through this comprehensive articles to know the details.

Already responded. Thanks
Plz Upload next lecture on emt
Sure dear. As the classes are resumed, we'll upload IA. Thanks
