Description
LaPO4 nanowires doped with 0, 1, 2, 3, 4 and 5 mol% Sm3+ were prepared by co-precipitation technique. These nanowires were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL), photoluminescence excitation (PLE) spectra and energy-dispersive X-ray spectra (EDS). The PL spectra exhibited 4 groups of emission peaks, which are assigned to the transitions from the excited state 4G5/2 to the ground states 6HJ with J = 5/2; 7/2; 9/2 and 11/2 of Sm3+ ions. The intensity of PL related to Sm3+ ion reached to a maximum when the Sm doping content was 2 mol%. The PLE spectra show 8 peaks, which are attributed to the absorption transitions from the 6H5/2 ground state to the 4K15/2, 4D3/2, 6P7/2, 4F7/2, 6P5/2, 4G9/2, 4I13/2 and 4I11/2 excited states.
