一般說明
Yttrium acetate tetrahydrate is a white, crystalline salt. The salt is soluble in water and mineral acids as well as solutions, such as methoxyethanol with diethylenetriamine, that complex with the Y3+ cations.
應用
Yttrium acetate is a common reactant in the synthesis of yttrium compounds including yttrium oxides and yttrium fluorides. Yttrium acetate is particularly useful because of its solubility in and low thermal decomposition temperature, which make it attractive for hydrothermal reactions and co-precipitation processing before calcination.
A major application of high-purity yttrium acetate is in the synthesis of sodium yttrium fluoride (NaYF4) nanoparticles. Typically, in these syntheses, yttrium acetate is mixed with oleic acid in octadecene and heated to form Y(oleate)3, which is reacted with ammonium fluoride and sodium hydroxide in methanol at modest temperatures (e.g. 50 C) to form NaYF4 nanoparticles. This synthesis offers great control over particle size and crystallinity and allows for easy incorporation rare-earth metal dopants.
Lanthanide-doped NaYF4 nanoparticles are one of the most studied materials for up conversion. These nanoparticles, which can convert two photons of near-infrared (NIR) light into visible light, have important in-vivo applications because of the deep tissue penetration abilities of NIR. For example, these nanoparticles have been used for in-vivo Zn2+ optical sensing, in-vivo ratiometric sensing of lymphatic inflammation,, and in-vivo sensing of peroxynitrite.

Drug toxicity is a long-standing concern of modern medicine. A typical anti-pain/fever drug paracetamol often causes hepatotoxicity due to peroxynitrite ONOO- . Conventional blood tests fail to offer real-time unambiguous visualization of such hepatotoxicity in vivo. Here we report a luminescent
