I have Reflectance data how can I convert it to transmittance?
Thans All in advance
Dear Dr. Endris Taju Seid,
the band gap value can estemated from the incident photon energy and absorption coefficient, which calculate from absorbance and film thickness.
Best regards
I agree with Khalid Haneen
As a first approach :
R = reflectance
T = Transmittance
They allow to determine absorbance A = 1 - R - T
Then, as a function of energy, bandgap will be the energy where A takes off from zero.
I am very interested in this paper.
