How we take an absorption spectra of rare earth doped glasses by uv vis spectrophotometry?

09 September 2014 1 3K Report

Which mode is prefered absorbance or reflectance mode and why? Can we also take the spectra in glass form by uv vis spectrophotometry ?

Sudhirkumar Munishwar

In addition to the answer of Thomas Brietzke I want to suggest that the glass samples should be optically polished for good absorption spectra.
