Abstract

Europium-doped yttrium oxide (Y2O3:Eu3+) nanophosphors were synthesized by wet chemical routes with both combustion and coprecipitation techniques. We explicitly illustrate the dynamics of Y2O3:Eu3+ nanophosphors with a particle size that is influenced by extrinsic stress and revealed by x rays and Raman scattering. The influence of Eu3+ activation on Raman spectra is illustrated. We demonstrate the significant enhancement of emission characteristics of ceramics synthesized from nanoparticles by using the combustion technique and by controlling the vacuum-sintering conditions.
