Yttrium nanoparticles are one of the most important stable or rare-earth compounds with a very wide range of important applications. For the production, some synthesis methods play an important role in the required size and morphology of nanoparticles as the main controlling factors for each application. It is being considered for biological applications because of it's high thermal, mechanical, and chemical stability, high corrosion resistance, and low toxicity.

Yttrium nanoparticles: In the field of materials science, these particles find a number of applications such as imparting color to the television picture tubes. These are also used in the making of plasma and flat panel displays. The property of red light emission is utilized in making fluorescent lamps and they are also used as additives in the coatings. It is used in high-temperature applications, paints, and plastics for guarding against UV degradation.

Moreover, these are also employed for making permanent magnets. In ultrafast sensors that are utilized in gray and x-rays. Some of the other applications include additives in steel, non-ferrous alloys, and iron. Yttrium nanoparticles have been broadly utilized in optics, electrics, and biological applications because of their favorable thermal stability, mechanical and chemical durability.

Yttrium nanoparticles can be employed as high efficient additives and functional composite materials like yttria-stabilized zirconia films. In addition to that, it is widely applied as a host material for various rare-earth dopants and is of interest for potential applications in biological imaging as well as photodynamic therapy.
