Deposition of indium oxide thin films assisted by gold nanoparticles in cyclohexane

Pulsed 532-nm light from a Q-switched neodymium: yttrium aluminum garnet (Nd:YAG) laser was used for depositing indium oxide (In2O3) films on a glass substrate immersed in a cyclohexane solution of gold nanoparticles and tris(2,4-pentanedionato)indium (In(pen)3). The photoinduced deposition was triggered by photoabsorption of the gold nanoparticles. The deposited In(pen)3 was sintered into semi-transparent and electroconductive In2O3 films by successive pulsed-laser irradiation. We demonstrated a one-pot single-step method to prepare electroconductive In2O3 films in a laser-irradiated area of the substrate.
