You can take the values directly from this link:

https://refractiveindex.info/?shelf=main&book=SiO2&page=Kischkat

n = 1.4432

k = 0.000020000

Absorption coefficient α = 1.6336 cm-1

You can change the type of material from the word "page".

thank you but i didn't find mesoporous TiO2 for exemple

i need mesoporous materials

I think these values help you at work:
