Upconverted Luminescence of BaGa2ZnO5 Powder Co-doped with Er3+/Tm3+/Yb3+
powder was researched through different preparation technology. XRD analysis proves that BaGa

ZnO

must be prepared in sealed environment and with more ZnO due to the phrolysis of ZnO. There are eight emission peaks in the upconverted emission spectrum of BaGa

powder excited by 980 nm LD
thereinto
480 nm and 798 nm peaks correspond to energy level transition of Tm
3+
ions
and other emission peaks correspond to energy level transition of Er
3+
ions. Moreover
the upconverted emission intensities under different exciting power were measured
and the multiple-photon absorption process of each emission peaks was obtained through fitting curve of exciting power-upconversion intensity. At last
the color coordinate of the sample powder was calculated according to the upconversion emission spectrum and standard data of CIE 1931. The color coordinate is (
x
=0.415 1
y
=0.479 4) and is close to the color coordinate of white light. It proves that the prepared sample powder has the application prospect in the field of white luminescence.
