英文摘要	nd3+-doped laf3 nanorods without -oh groups were synthesized via a simple thermolysis method in trioctylphosphine oxide (topo) solvent. ftir spectrum indicates that topo molecules have been coordinated to laf3:nd nanorods surface, which reduce the number of -oh groups on the nanoparticles surface effectively. the structure and morphology of as-synthesized nanorods were characterized. the possible grow mechanism of laf3:nd nanorods has been also discussed in detail. the topo capped laf3:nd nanoparticles preferentially grow along the <0 0 0 1> orientation under high temperature. based on the absorption spectra and judd-ofelt theory, higher value of emission cross-section for f-4(3/2)-> i-4(11/2) transition of nd3+ was calculated to be 3.22 x 10(-20) cm(2). the strong fluorescence intensity of laf3:nd nanorods in chloroform demonstrates that these nanorods are promising luminescence materials.
