The change of matrix structure can provide different local environment for doped rare earth ions
which offers us an effective way to adjust the luminescence property of active ions. In current paper
the influence of the matrix structure on the luminescence properties of Pr
3+
and Eu
3+
doped fluoride nanoaprticles has been investigated with laser spectroscopic method. The characters of fluorescence emission from single doped and co-doped nanoparticles have been studied too. It was found that the intensity and the color purity of the fluorescence emission were improved greatly by co-doping another kind of ion to the doped nanoparticles as well as by changing the matrix of the nanoaprticles. The experimental observations were discussed based on the energy level structure of doped ions and the symmetry characteristics of nanocrystals.
