How can I get a nice vibrational-mode signal in the Raman spectra of a thin film?

I have prepared thin films with thickness around 300nm, but I got a low signal of the vibrational mode of my materials. Does anybody know if it is because of the thickness of my thin films or...

Can anyone suggest the most accurate method for calculating the band gap values of powders and thin films materials?

I am in doubt about which method i may use to calculate band gap of thin films, if the Kubelka-Munk method using diffuse reflectance spectra or the Tauc method using absorption spectra.

Rinat Ismagilov

I used BET method to determine the surface area for carbon nanotubes. If you have sample with enough surface area this method may help to you. Good luck!

André Luiz Menezes de Oliveira

Dear Rinat Ismagilov, Thanks for your help! But as I know BET is applied for solid samples, I don't know if this method is adequate to determine the surface area for thin films, if yes could you explain me how it is done?

Dear André Menezes de Oliveira ,

I'm not shure will it help or not. Anyway, I would to say, that this method may work in your case. This method based on adsorption of gas molecules and works on any solid sample. To determine the adsorption effect by weight you need "huge" surface area. If you are speaking about flat samples (without pores, tubes-like structure, wrinkles and etc.)... this method fails.

Thanks Rinat Ismagilov for helping me!

Well, i didn`t know yet about BET for thin films but I saw there is an accessory for doing this kind of analysis.
