文摘

Ablations of Ti metal target were carried out in DI water and in 0.001 M SDS solution for different times using PLAL process. Different characterization studies have been carried out to confirm the growth of TiO2 nanoparticles in both the liquid mediums. Anatase phase TiO2 nanoparticles were obtained in DI water and rutile phase in 0.001 M SDS aqueous solution. In surfactant solution, longer time ablation leads depletion of SDS molecules causes growth of anatase phase for 90 min. Our studies confirmed the role of liquid ambience conditions variation over the different phase formations of nanoparticles.
