Synthesis and Characterization of Monodispersive In2O3 Particles


Article Preview

Monodispersive and uniform particles have many potential applications. The objectives of this study are trying to synthesize and control the morphology of monodispersive indium oxide (In2O3)particles through hydrothermal process with the help of PVP (polyvinylpyrrolidone) and urea additions. Various cubic, ellipse, or shuttle-like In2O3 particles were synthesized by using hydrothermal conditions (65-85oC). The effects of Sr nitrate were studied. Spherical particles could not be synthesized. The aspect ratio of the In2O3 particle reduced as the concentration of Sr nitrate increased. Crystalline In2O3 phase appeared above 300oC.
