Abstract

The Y

∶ Er

nanometer phosphors coated with SiO

was synthesized by the microemulsion method. The X-ray diffraction results showed that the as-prepared powders were cubic phase of Y

. The TEM pictures demonstrated that the powders have the nearly spherical and the average diameter of the particles was in the range of 60~80 nm. Under the excitation of 980 nm diode laser

a very strong green emission centered at 562 nm and a red emission centered at 660 nm were observed

which were assigned to the transitions of

respectively. The research on luminescent intensity and the exciting power relations revealed that this up-conversion process was a two-photons absorption process. Because Y

(nucleus)/SiO

(shell) has highly effective performance on the up-conversion luminescence and was easy to dissolve in the water and united with organic matter and biological member

the application of this nanometer nuclear-shell structure material in the biological fluorescence mark domain is significance.
