How we can explain the increase in transmittance with the decrease of refractive index for ITO thin film near IR?

The behavior of decreasing refractive index n for wavelengths greater than 700nm is an important result, because it corresponds transmission increasing of ITO /glass at near-infrared wavelength

Why we use metal oxide and increase the doping agent .some of the peaks disappear?

if the matrix was metal oxide and use any dopant material to get new physical properties we observe that some peak in the XRD pattern will disappear.

Why for metal oxide we need high dopant in order to appear in XRD?

I notice for a metal oxide when we we need this metal oxide to be doped , we must use doping with at least 8% wt in order to see some peaks belong to the dopant material in XRD pattern, other wise...
