PL spectra indicate that the emission bands at 515 and 542 nm correspond to the 2H(subscript 11/2)→4I(subscript 15/2) and 4S(subscript 3/2)→4I(subscript 15/2) transitions of Er(superscript 3+), respectively. In the samples, the cerium dopant exists as Ce(superscript 3+) and Ce(superscript 4+). Ce(superscript 3+) sensitizes Er(superscript 3+) and enhances the luminescence intensity of the doped nanorods remarkably and energy transfer from Ce(superscript 3+)→Er(superscript 3+) was observed.
