calculate optical conductivity from uv-visible spectroscopy

In this video I will discuss about optical conductivity and its calculation from UV-Visible absorption data.
Optical conductivity is very important property to measure electronic states of a material.
It is closely related with dielectric function.
It depends upon
1. Optical bandgap
2. Refractive index
3. Absorption coefficient
4. Incident photon frequency
5. Extinction coefficient

really amazing good job

[@alizain8321]

Totally impressed by your method

[@nanotutes]

Thanks for your comment

[@Don-np2ms]

Totally impressed by your method ...🥰🥰

[@nanotutes]

Thanks for your comment.

[@jolly_rogers154]

why did you use $ in both sides of a specific column, like; $F$11?
if the material thickness is 50um or 100nm apart from 1cm, then how will I write it the formula section?

[@pssushree9751]

Thank you for the demo. Which research article has to be cited for this?
Any comment on how to corelate optical and electrical conductivity?

[@carbonmani]

good explanation and easy method also

[@nanotutes]

Thanks for liking

[@rizwanjmrt9834]

helo sir i am confused in units of optical conductivity, these come out to be per second? What does mean by this?

[@samialabsi9808]

Thanks for this demo.
Can I know how you got the relationship between the refractive indiex and the transmittance?
How did you arrive at the equation of the refractive index? Any reference?

[@nanotutes]

Send a request for reference at.

easy method good explain for children's

[@nanotutes]

Thanks boy.

[@misbahkiran4032]

Amazing video❤ sir plz provide reference or any other research paper related to it .i need it

[@asst.prof.rohitnikam729]

Thanks for video. For thickness of thick film what is criteria.

[@nanotutes]

Units have been given in video.
And for thick film one can use caliper or something like that.

[@ayanroy9185]

Method is simple and great.
I will be obliged if you kindly provide the journal paper or any documents corresponding to the refractive index formula from percentage transmittence for polymer thin films.
I need the reference corresponding to this formula.
Thanking you

[@nanotutes]

Plz provide your email address

[@GedefawMebratie]

thank you.

[@faheemwani1996]

sir how to calculate dielectric relaxation time from UV data

[@ragunathl4410]

Dear sir, I have calculated refractive index for BN powder from absorption data...But it shows 0.13-0.15.but actually its 1.57-2.67 from journals. How could i interrelate for this

[@shahfahad1854]

its difficult from UV due to some technical issues, you can calculate it from transmission spectra

[@rebazobaid1662]

i am interested in your excell sheet.

[@rajupatel7209]

Good work

[@nanotutes]

Thanks

[@sajibbiswas4795]

Thank you for this helpful video.
Can you please provide me the reference of this formula?

[@asst.prof.rohitnikam729]

Kindly provide some references above this method,also with refractive index references, band gap,

[@nanotutes]
