| Research Abstract |
The objective of the present study was to prepare uniform thin films at low temperature, for instance r. t., made of nano-particles with some functions for environmental cleanup. The TiO2 nanoparticles with N atoms, thermally stable up to 500℃, could be prepared in the pulsed laser ablation(PLA) in water with N atom involved acid or base. It was found that the uniform thin films could be obtained at r. t. by fabricating the nanoparticles prepared in the PLA in diluted ammonia solution. As the way to low temperature thin film preparation method is developed, one can continue to expand this field of technology.
