Abstract EN
Distinct effects of the SiO2 shell on fluorescence properties of LaF3:Nd3+/SiO2 core/shell nanoparticles were demonstrated by annealling the nanoparticles at different temperatures.
Emission spectra, excitation spectra, and decay curves of the nanoparticles were measured.
A significant improvement of fluorescence intensity was observed for LaF3:Nd3+/SiO2 core/shell nanoparticles annealed at 900∘C.
The phenomenon is ascribed to the change of environment of LaF3:Nd3+ core which is imposed by SiO2 shell.
And the change is confirmed by the excitation spectra.
It provides a useful way to improve fluorescent intensity of the SiO2-coated LaF3:Nd3+ nanoparticles.
The lifetime for nanoparticles annealed at 900∘C shows a slight decrease contrast with nanoparticles annealed at 400 and 600∘C.
This is caused by the higher phonon energy of SiO2 than that of LaF3.
