Hello,
am working with luminescence spectra, including excitation and emission spectra. When you makes an initial characterization of a sample should be done first?
an absorption spectrum?
At what wavelength excitation should be performed to see the desired effect?
Particularly when...
Hello, I am trying to determine the band gap of an amorphous material (a glass sample) and I read that you can do this from the determination of the optical absorption edge.
From this kind of measurements you fitt an equation of the type (αhν) = B (hv-Eo) 2.
my question are:
1 - is it...
