Abstract

The powders of Ho

Yb:(LaLu)

were prepared by citric acid combustion method. The preparation conditions of the powders were determined. The as-prepared particles are of near-spherical shape

and weak agglomeration

the average particle size was about 55 nm. The effects of different mole fraction Ho

and Yb

on the fluorescence spectra of the powders were studied. Under the excitation of 980 nm

the powders can emit blue-ray appeared at 484 nm

corresponding to the energy level transition of Ho

from

green light appeared at 551 nm

corresponding to the energy level transition of Ho

from

and red light at 660 nm

corresponding to the energy level transition of Ho

from

. The upconversion luminescence mechanism of Ho

-Yb

in co-doped system was discussed.
