phosphors were synthesized by high temperature solid-state method. Structures of the samples were investigated by X-ray diffraction. The excitation spectra and emission spectra were measured. With the increase of Yb
3+
concentration
the visiable emission intensity decreases but the near-infrared emission increases. So the cooperative energy transfer from Tb
3+
to Yb
3+
is demonstrated. The luminesence lifetime decay curves of Tb
3+
(544 nm) with different Yb
3+
concentrations were measured. The dependence of lifetime
energy transfer efficiency and quantum efficiency on Yb
3+
concentration were obtained. The highest quantum efficiency is 125.5%. The emission of Yb

(977 nm) is just above the band gap of crystalline sillicon
so this material can be applied in the sillicon-based solar cells to progress the conversion efficiency.
