[Studies on the properties of frequency upconversion of Yb3+/Er3+ codoped absolute oxides].
2006
Samples of Er~(3+)/Yb~(3+)codoped 3CaO-Al_2O_3-3SiO_2 compounds were prepared,and the properties of frequency upconversion of the samples under the excitation of 980 nm diode laser were studied.Green and red emissions centered at 523,547 and 656 nm,corresponding to the transitions()~2H_(11/2)→()~4I_(15/2),()~4S_(3/2)→()~4I_(15/2),and()~4F_(9/2)→()~4I_(15/2),respectively,were observed.The dependence of the upconversion fluorescence intensity on the pumping power,and the phonon energy of each sample were observed,and the mechanism of frequency upconversion based on these two items was discussed.
