International Journal of Nanomanufacturing (IJNM), Vol. 9, No. 3/4, 2013

Abstract: The monodisperse colloidal NdF₃ nanorods were synthesised via one-step thermolysis of Nd(CF₃COO)₃ 3H₂O in a hot trioctylphosphine oxide solution. The resulting product was characterised by Fourier transform infrared analysis, transmission electron microscopy and photoluminescence spectroscopy. The rod-like nanocrystals possess well shaped fenestral structures. Optical spectra exhibited the colloidal NdF₃ nanoparticles possessing typical Nd³⁺ ion absorption and photoluminescence mission. The emission cross-section of ⁴F_3/2 → ⁴I_11/2 fluorescence transition was 2.12 × 10-20 cm², and comparable with some laser glasses.
