Raul Montes

You can prepare a thin film or a pellet. You can use some transparent polymer to spin coat on a substrate. If you want UV absorption use fused silica or quartz substrates.

Ayushi Mishra

Dear Raul Montes Sir,

if I want to take their spectra in an aqueous medium.

Papiya Saha

You may use diffuse reflectance spectrscopy with powder sample holder attatchment to do UV.

Papiya Saha kindly tell how to perform. with references.
