Abstract
Europium-doped yttrium oxide nanophosphors were synthesized by wet chemical routes with both combustion and coprecipitation techniques. We explicitly illustrate the dynamics of nanophosphors with a particle size that is influenced by extrinsic stress and revealed by x rays and Raman scattering. The influence of 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.
