- Abstract
- Eu-doped Y2O3 nanophosphors were prepared using combustion synthesis. In this method, urea was employed as a fuel. The particle size was estimated to be in the range of 10-20nm as determined by X-ray diffractometry and transmission electron microscopy. The photoluminescent and cathodoluminescent spectra are described by the well-known D-5(o)-> F-7(J) transition (J = 0, 1, 2, etc.) of Eu3+ ions with the strongest emission for J = 2. The optical properties of nanophosphors were compared with commercial with an order of micrometer size. The effects of urea-to-metal nitrate molar ratio and the other synthesis conditions on the particle size and luminescent properties will be discussed in detail. The red emission of Eu-doped Y2O3 nanophosphors is promising materials not only in high-resolution screen but also in telecomunication as well as in biosensor. (c) 2006 Elsevier B.V.
