| 中文摘要 | multicolor and monodisperse gd2o3: ln (ln = eu3+, tb3+, dy3+, sm3+, yb3+/er3+, yb3+/tm3+, and yb3+/ho3+) nanocrystals (ncs) with narrow size distribution were prepared by a homogeneous precipitation method followed by a subsequent calcination process. x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), fourier transformed infrared (ft-ir), thermogravimetric and differential thermal analysis (tg-dta), photoluminescence (pl) spectra, cathodoluminescence (cl) spectra, and kinetic decays were employed to characterize the samples. the results show that the gd2o3: ln ncs can be directly indexed to cubic gd2o3 phase with high purity. and the possible formation mechanism and the chemical reaction of each step to form spherical gd2o3: ln ncs are proposed according to the concerned analysis. upon ultraviolet and low-voltage electron beams excitation, gd2o3:ln (ln = eu3+, tb3+, dy3+, and sm3+) ncs exhibit respective bright red (eu3+, d-5(0) -> f-7(2)), green (tb3+, d-5(4) -> f-gamma(5)), blue (dy3+, f-4(9/2) -> h-6(13/2)) and yellow (sm3+, (4)g(5/2) -> h-6(7/2)) down-conversion (dc) emissions. under 980 nm nir irradiation, gd2o3: ln (ln yb3+/er3+, yb3+/tm3+, and yb3+/ho3+) exhibit characteristic up-conversion (uc) emissions of er3+, tm3+, and ho3+, respectively. |
