Abstract
CaSiO3:(Eu2+, Dy3+) nanorods were synthesized by microwave irradiation process with assistant of polyethylene glycol (PEG)-1000. The X-ray diffraction results show that the obtained samples are of β-CaSiO3 phase with perovskite structure. The TEM images show that the obtained samples are of nanorods with diameter around 40 nm and length ranging from 0.6 to 1.2 μm. PEG-1000 plays an important role in the formation of claviform morphology. The excitation and emission spectra of CaSiO3:(Eu2+, Dy3+) samples show characteristic transitions of Eu2+ ions. All samples give a green emission peaked at 512 nm when they are excited at 366 nm. The co-doped Dy3+ ions enhance the luminescence intensity greatly but have no obvious influences on location of emission peak. CaSiO3:(0.05Eu2+, 0.03Dy3+) samples give the highest luminescence intensity.
