Abstract

SiO

∶Eu and Y

SiO

∶Tb nanopowders were prepared by sol-gel method. The structure

morphology and luminescent properties were analyzed by X-ray diffraction

scanning electron microscopy and so on. The luminescent properties of Eu

and Tb

doped yttrium silicate nanopowders with different concentration were investigated. The main emission peak of obtained Y

SiO

∶Eu nanopowders is at 612 nm excited by UV light

ascribed to the transition of

of Eu

. The main emission peak of Y

SiO

∶Tb nanopowders is at 540 nm

ascribed to the transition of

of Tb
