Lanthanum oxide nanoparticles
Lanthanum is a Block F, Period 6 element, while oxygen is a Block P, Period 2 element. Lanthanum oxide is an odorless, white solid. It is insoluble in water, and soluble in dilute acid. Lanthanum oxide nanoparticles have high photoelectric conversion efficiency.
The morphology of lanthanum oxide nanoparticles is spherical, and they appear as a white powder. They are strongly hygroscopic. Lanthanum oxide nanoparticles are graded as irritant, and can cause irritation to the skin, eyes, and related breathing difficulties.
