Main subject among January experiments was photochemical deposition of silver nanoparticles on titania substrates.This experiment was conducted and directed on investigtion of first stages of the deposition hence nucleation stage. For that matter illumination time was set on 5 min.
Five different silver nitrade solution concentration (0,5, 1, 2, 5 10mM) were investigated under three levels of laser light intensity ( low, meidum, high). The blue laser ( 405nm) was used. The titania was previously annealed in 500 Celcius degrees.
It is expected that different conditions should result in different microstructure formation.
The samples will be examined by HR SEM imiging in following months.
