Cerium oxide rice grain like nanoparticles have been synthesized using wet chemical hydrothermal synthesis method. Hydrothermal synthesis method provides nanoparticles with unique dimension and shape due to supercritical synthesis conditions than conventional precipitation techniques. The hydrothermal synthesis of Cerium salt in the presence of urea produces Cerium carbonate hydroxide nanoparticles with rice-grain morphology, which are reduced into Cerium oxide by heat-treating at 600°C, for 4 hours, without changing its morphology. The formation of Cerium carbonate hydroxide with orthorhombic crystal structure and Cerium oxide with cubic crystal structure were confirmed by X-Ray Diffraction [XRD] spectroscopy studies. Thermo-gravimetric analysis [TGA] in inert nitrogen atmosphere and ambient air provides the reduction temperature of hydroxide and carbonate is about 600°C. Scanning electron microscope [SEM] studies show the uniform rice grain like morphology of as-prepared Cerium carbonate hydroxide and Cerium oxide, due to the reduction at elevated temperature and crystalline structural deformation Cerium oxide shows cracks and porous on its surfaces.

Cerium oxide, in addition to its catalytic properties, is also known for its optical properties such as ultraviolet (UV) radiation filtering and a relatively high refractive index ( n > 2 ), which makes it an excellent candidate for multifunctional coatings. Here, we focus on the optical properties of thin deposits (≲2 μ m) of densely packed C e O 2 nanoparticles, which we assemble using two evaporation-based techniques: convective self-assembly (CSA, a type of very slow blade-coating) to fabricate large-scale coatings of controllable thickness—from tens of nanometres to a few micrometers—and microfluidic pervaporation which permits us to add some micro-structure to the coatings. Spectroscopic ellipsometry yields the refractive index of the resulting nano-porous coatings, which behave as lossy dielectrics in the UV-visible regime and loss-less dielectrics in the visible to infra-red (IR) regime; in this regime, the fairly high refractive index (≈1.8) permits us to evidence thickness-tunable anti-reflection on highly refractive substrates, such as silicon, and concomitant enhanced transmissions which we checked in the mid-IR region.
