Abstract

Near infrared (NIR) emitting LaF3:Ln3+ (Ln3+→Nd3+, Er3+, Yb3+ and Ho3+) singly doped nanoparticles (NPs), with an average size of 5 nm, have been synthesized using simple co-precipitation route. Nanoparticles were functionalized with oleic acid. FTIR spectra revealed the prescience of chemisorbed oleic acid on the surface of nanoparticles. 10 wt % of LaF3:Nd3+ nanoparticles were incorporated into epoxy by solution mixing method. The LaF3:Nd3+-Epoxy Nanocomposites showed good transparency along with prominent NIR emissions at 880 nm, 1053 nm and 1330 nm on excitation at 575 nm.
