When adding the semiconducting particles to the polymeric matrix, any changes in (Lamda) of the matrix, meaning no changes in the gap energy of the latter. This phenomenon does not follow the literature because of the mixture of conducting particles and insulating matrix. I mention that in the reflectance measurements, the effect of semiconducting charge is seen, i.e. adding semiconducting charge decreases the gap energy of the matrix.
In the attached file, an example of a measurement made using UV-Vis spectroscopy.
Can anyone help us give an interpretation of this behavior? thank you.

I would assume that the diameter of the particles relative to wavelength is very important. If the diameter is very small relative to wavelength, you get an effective medium, whereas if not than it is like a mosaiced surfaces. I hope this helps!
