This method is based on photocatalytic properties of titanium dioxide. The UV photon creats electron hole pair. This electron can reduce the silver cation which then deposits on titanium dioxide substrate. At first this method was used for creation of homogenius silver layer with well controlled thickness. First results and literature announcements showed that in the first stage this proces leads directly to nanoparticles deposition.

In my experiment the source of light was 405nm laser. Silver atoms came from a few solutions: 1) solution used previously for electroless deposition, 2)succinimide, 3)solution of silver nitrate.

Obtained microstructure was 0,5um squares, below 20nm particles with nanorods and about 70nm particles respectively for mentioned solutions.

Silver nitrate was the best solution and it was chosen for next research.

There is is an issue with results reccurence.
