Hello sir, can you please confirm in equations {(F (R) hv)2 and (F (R) hv)1/2}, which is for direct bandgap and which is for indirect bandgap?

Is there any scientific article that I could refer and cite for this Kubelka Munk calculation? I find this very helpful and most of articles I found include the thickness of thin film (t) in the equation like =F(R)/t while I'm using powder sample. Your respond is much appreciated. Thank you so muchh

Yes: please search on google

How can we calculate the refractive index(n), extinction coefficient (k), optical and electrical conductivities and dielectric relaxation time from DRS?
