Abstract There have been few reports on studies of energy upconversion from Yb3+-doped materials based on oxide, fluoride or oxyfluoide, because researches commonly considered that Yb3+ was only a good sensibilizer. This paper reports the properties of energy upconversion of Yb3+-doped materials based on ZrF4. The rare earth Yb3+ was doped in the ZrF4 glass under the specific condition. Using 980 nm laser as an excitation light, the upconversion fluorescence spectra of the sample were measured, and the red band, green band, blue band and purple band observed, respectively. The peaks were at 412, 478, 558 and 671 nm，respectively. This paper reports the upconversion from Yb3+ standard energy level to Yb3+ energy level 2F7/2.
