| Abstract: | A series of Er3+, Tm3+ and Yb3+ doped Gd3Ga5O12 nanocrystals were prepared by a combustion method. The X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and upconversion (UC) emission spectra were used to characterize the samples. The results of XRD indicate that Gd3Ga5O12: Er3+, Tm3+, Yb3+ nanocrystals with cubic phase can be obtained. Under the excitation of a 980 nm laser, the different rare earth ions doped Gd3Ga5O12 nanocrystals show upconversion luminescence involving the green emission attributed to the 2H11/2→4I15/2, 4S3/2→4I15/2 transitions of Er3+ ions, respectively, the red emissions assigned to the 4F9/2→4I15/2 transitions of Er3+ ions and the 1G4→3F4 as well as 3F2,3→3H6 transitions of Tm3+ ions, respectively, the blue emission attributed to 1G4→3H6 transitions of Tm3+ ions, and the near-infrared assigned to the 3H4→3H6 transitions of Tm3+ ions. The CIE coordinates for the samples are calculated. The dependence of their upconversion luminescence properties on Yb3+ ion concentration is investigated. |
