Red-emitting Y 2 O 3 :Eu 3+ and green-emitting Y 2 O 3 :Tb 3+ and Y 2 O 3 :Eu 3+ , Tb 3+ nanorods were synthesized by hydrothermal method. Their structure and micromorphology have been analyzed by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The photoluminescence (PL) property of Y 2 ...
One kind of europium (III) ternary complex was synthesized, and its photoluminescence properties were investigated. This complex exhibits broad excitation band in near-UV range, and strong red emission which is due to the 5 D 0 – 7 F j transitions of Eu 3+ ions. The luminescence quantum yield for the Eu 3+ complex is 0.17. Thermogravimetric analysis...
