Abstract:Polycrystalline lanthanum oxalate (LaOX) nanorods (NRs) were succesfully synthesized using reverse micellar (RM) method. The study espouses the versatility of the reverse micellar method forming monodisperse, stable nanorods at room temperature. The as-synthesized LaOX nanorods were characterised by different techniques. Result shows that the nanorods of LaOX with aspect ratio 10.2:1 have preferred growth direction of (020). The pure phase synthesis of the nanorods was confirmed from fourier transformed infrared (FTIR) and X-ray diffraction (XRD) analysis. The thermo gravimetric analysis (TGA) and differential thermal analysis (DTA) of the as-synthesized nanorods were perfomed to observe their thermal degradation. Synthesized nanorods are fluorescent having emission maximum at 329 nm. Fluorescence resonance energy transfer (FRET) phenomenon has been observed between LaOX nanorods (energy donor) and naphthalimide (NAP) derivative (energy acceptor) and this mechanism can be helpful for sensing of NAP or NAP like molecules used as antioxidative in living systems.
