I have photosensitive material (CZTS) in powder form. UV-Vis only give absorption in solution.PG instruments T60U spectrophotometer is available.How can I do this?
Disperse your powder in the solvent (maybe you need to supersonic) and when you get a stable suspension, you can use it to test the Uv-vis.
Regular solution constant or interaction parameter defined as ω = = zN[e_ab - (e_aa + e_bb)/2] where z is coordination number, N=N_a+N_b number atoms in solution, and e_ab/aa/bb is interaction...

I have metal salt and thiourea, ethanol and water 30%V and 70%V. I stir it for 10 hours at RT then 2 hours at 50°C, and then dry from 20 hours at 110°C. No powder forms. Can anyone please explain?
