ions were synthesized by hydrothermal method. The upconversion emission spectra excited by 980 nm were measured. The developments of upconversion emission characters are studied on the synthesis temperature
the reaction time and Tm

concentration. The strongest blue emission is obtained under the excitation of 980 nm laser when synthesis temperature is 180℃
