Structural and Optical Investigations of Ce3+/Mn2+-Doped LaPO4 Phosphors
Lanthanum orthophosphate (LaPO 4 ) and La 0.95− x Ce 0.05 Mn x PO 4 ( x = 0.00, 0.03, 0.10) phosphors were synthesized by a simple and cost-efficient co-precipitation method and the formation of LaPO 4 nanorods with a monoclinic P21/n crystal structure was observed.

nanorods with a monoclinic P21/n crystal structure was observed. X-ray diffraction pattern analysis indicated a slight distortion of the LaPO

crystalline structure and an increase of the lattice strain as a consequence of the Mn

and Ce

dopants incorporation in the host matrix. Scanning electron microscopy revealed that the microstructure of all powders consists of agglomerations of nanorods, which are around 17 ± 3 nm in diameter and length ranging from 100 nm to 300 nm. Electron paramagnetic resonance measurements have indicated the presence of Mn
2+
in isolated species, but also as agglomerates. Ce
3+
and Mn
2+
doping of LaPO
4
resulted also in a decrease of the band gap up to 4.70 eV compared to the un-doped sample. Because of an energy transfer effect from Ce
3+
to Mn
2+
ions, green emission of Mn
2+
ions at around 550 nm was observed upon 275 nm excitation. |
