Abstract

:Pr

nanoparticles were synthesized by femtosecond pulsed laser ablation method

and the up-conversion properties of the particles were investigated. The nanoparticles can be obtained under certain laser power intensity. With the increasing of laser intensity and pulse repetition frequency

the yield of the nanoparticles increases. The diameters of these spherical particles are smaller than 50 nm. An emission band centered at 510 nm can be observed in the emission spectrum under 976 nm excitation. The emission intensity increases with the amount of the nanoparticles.
