Synthesis and luminescent properties of Eu~(3+)-doped YVO_4 by using a mild hydrothermal process

摘要

Nanoscale YVO_4:Eu~(3+) phosphor has been synthesized by a mild hydrothermal reaction at various experimental conditions. The particle and luminescent properties of nanophosphors were characterized with X-ray diffraction, electron microscopy and photoluminescence. It has been found that pH value play a key factor both controlling particle size and luminous efficiency.
