Particle Size Control of Y2O3:Eu3+Prepared via a Coconut Water-Assisted Sol-Gel Method
Journal of Nanomaterials
Eu3+-doped Y2O3nanoparticles were produced through proteic sol-gel technique, and the adjustment of pH was tested in order to control the particle size of the powders. A strong correlation between the initial pH and the temperature of crystallization was observed, allowing the production of particles with controlled diameter from 4 nm to 50 nm. The samples were characterized by X-ray diffraction, high-resolution transmission electron microscopy, optical microscopy and photoluminescencedoi:10.1155/2011/469685 fatcat:6dnpset525d3zptw7zrldhu77y
